The correct preposition to be used in the sentence is "in". When we use ability to show expertise in a particular subject, we use the preposition "in" with "ability". Hence, option D is the correct answer.

By using the article a, we’ve created a general statement, implying that any cup of coffee would taste good after any long day. Hence, option C is the correct answer.

The use of 'lend' is correct in the sentence as it means to give something to somebody expecting that it'll be returned after some time. "Will" takes first form of verb after it. Hence, option B is the correct answer.

The given sentence is in simple past tense. Here, the verb "have" will be used as a main verb and not as an auxiliary verb. Since the sentence is in simple past tense, we will take the V₂ form of "have", i.e. had. The use of conjunction "but" shows the opposite of what was expected in the first part of the sentence. Therefore, we will use "none" here. Hence, option C is the correct answer.

Let's understand the meaning of the given words :-
Reward = a thing given in recognition of service, effort, or achievement.
Award = a prize or other mark of recognition given in honour of an achievement.
Profit = a financial gain; advantage; benefit.
Prize = a thing given as a reward to the winner of a competition or in recognition of outstanding achievement.
The noun that makes sense in the sentence is "reward" as the police are giving something for the efforts put in finding the information about the stolen money.
Hence, option A is the correct answer.

The sentence is in past tense in indirect speech, therefore ‘had finished’ is the most appropriate for the blank. Hence, option C is the correct answer.

Here the sentence is about two things ‘my food’ and ‘my repose’. Both which refers to the first and the second is the most suitable response. Hence, option C is the correct answer.

The given sentence is a future real conditional sentence. Such sentences describe what you think you will do in a specific situation in the future as in the given sentence. The structures of such sentences are:

[If / When ... Simple Present ..., ... Simple Future ...]

[... Simple Future ... if / when ... Simple Present ...]

Therefore, we need to use simple present tense in the second clause beginning with "when". Only option A has the verb, i.e. stops which belongs to simple present. Hence, it is the correct answer.

Let's understand the given phrasal verbs :-
