There is no error in the given sentence as cattle is treated as plural noun in English language and in the sentence a plural verb is used with it. So the sentence is totally grammatical. Hence, option D is the correct answer.

In the third part of the sentence, when comparison is done using ‘as…as’, the normal form of the word is used, not the comparative or the superlative form. ‘Clusters’ is plural, so ‘are’ will be used. So, the correct form is ‘are as big as’. Thus, Option C is the correct answer.

Option B has the grammatically incorrect part. In the second part of the sentence, the relative pronoun ‘that’ is used instead of ‘who’ or ‘which’ after adjectives in the superlative degree. Here ‘least’ is an adjective in the superlative degree and therefore ‘which’ is wrongly used in the sentence.

In the third part of the sentence, we need to use ‘yet’ after the phrase ‘furniture in order’ to make the sentence grammatically correct. Thus, Option C is the correct answer.

Option B has the grammatically incorrect part. The error lies in the incorrect usage of a pronoun. “Their” is a related term for “they’re”, while one refers to a place (there). “Their” is the possessive plural pronoun belonging to, from, of, or relating to them. It is the correct word. The segment requires “their” as it reflects a relationship between men and the children.

The error lies in the incorrect usage of a preposition. Structures using “such” and “so” are similar in meaning and different in construction. The main difference is that “such” takes a noun phrase, while “so” takes an adjective. As per the above segment, “societies” is the noun, and “such” is the correct preposition.
The correct sentence would be:

He believed that such societies create the best conditions for individual development and social improvement.

Hence A is correct.

Option C has the grammatically incorrect part. The error lies in the incorrect usage of the verb. “Does” is the third person singular present tense of the verb “do”. While the verb “do” is used when referring to more than one person or thing, the word “does” is used in sentences that refer to a single person or thing. For example: “It does look nice on you. They do look nice together.”

The error lies in the incorrect usage of a verb. The sentence is in simple present tense. In a simple present sentence where he, she, it or a name is the subject, verbs can end in “-s or –es” depending on the way the verb ends.

The correct sentence would be:

It emerges from within constraint like a breath, it is about breath, it is about breathing.

Hence A is correct.

There is an error in the third option. The sentence is written in past tense as confirmed by the verb "became" (past form of become) and "found" (past form of find). So instead of "are", we should use the verb "was" as the subject is singular i.e. 'his father'.

The preposition “with” should be replaced by “from” as to represent present time or future time, the preposition “from” is used; e.g. from today, from tomorrow, from next year, etc.

The correct sentence is –

“The manager is pleased to sanction one special increment to all the employees from this month.”
