The underlined part is grammatically incorrect. Renunciation is a noun which means the act of renouncing something (rejecting, disowning, or disclaiming as invalid). There is no single thought that comes across one’s mind which is undesirable. Many thoughts came across our minds some of which are undesirable. Also, the noun (actions) after "and" is plural. Therefore, we will use "thoughts" in place of "thought".

Hence, option C is the correct answer.

 The underlined part is grammatically incorrect. We cannot use continuous with verbs whose meanings are already continuous (e.g.: like, love, know, etc.), it would make the sentence superfluous. So, replace ‘if you are liking it’ with ‘whether you like it’. Hence, option C is the correct answer.

“The nearer house“ will be replaced with “the nearest house” as

1) “The“ is used with superlative degree

2) Superlative degree is used to show the upper or lower limit of something

Hence, option A is the correct answer.

The underlined part is grammatically incorrect. After auxiliary verb ‘are’, an adjective is needed. ‘Committed’ is an adjective, so, it should be used in place of verb ‘commit’. Also, either it should be vocations or a vocation. Only first option is appropriate i.e. ‘a vocation’ has been used in it. And, here, ‘that’ will be used as ‘that’ is used to point out something. Thus, “committed not to live with a vocation that” is the most suited.

Hence, option A is the correct answer.

The underlined part is grammatically incorrect. With ‘both’ (denoting more than one), we use plural noun i.e. ‘parents’. With plural noun, plural verb should be used i.e. ‘delight’. And with verb ‘delight’, we generally use preposition ‘in’. Conjunction ‘that’ should be used in place to ‘this’, which is used to introduces a subordinate clause. Thus, the most suited one is “parents delight in the fact that”.

Hence, option A is the correct answer.

 “Would not be” will be replaced with “will not be” and the structure is as follows:

If + present simple + will-future or Modal with infinitive

Hence option A is the correct answer.

The underlined part is grammatically incorrect. ‘People’ is a plural noun, so, it doesn’t require ‘s’ after it to make it plural. Thus, it should be ‘people’. ‘There’ is used to focus attention on something which is not the case here. We need ‘their’ which is used when something is belonging to or associated with the people or things previously mentioned or easily identified. Thus, “many people lose their balance” is the most suited.

Hence, option D is the correct answer.

The underlined part is grammatically incorrect. The subject of the given sentence is ‘ability’ which is singular so, we need a singular auxiliary verb after it. Thus, ‘is’ should be used in place of ‘are’. And we need preposition ‘by’ in place of preposition ‘to’. ‘By’ means with aid of; through the act or agency of. As, one’s ability will be determined by something. Thus, “is largely determined by” is the most suited.

Hence, option A is the correct answer.

The underlined part is grammatically incorrect. The verb “command” doesn’t take “on” after it. The two prepositions that can come after command are – “of” and “over”. But the option C uses “better” before command which makes it erroneous. Hence, option A is our correct answer.

 “No soon the Chief Minister” will be replaced with “no sooner did the Chief Minister as “no sooner” is the correct adverb and the sentence is in past tense , thus “did” will be used as we use inversion after the “no sooner”.

Hence option C is the correct answer.
