Select the sentence with the appropriate use of preposition.

Correct option is A

The correct sentence with appropriate use of preposition is option (a) They rise with the morning lark and labour till almost dark.
Explanation:

• The preposition “till” is used to indicate the continuation of an action up to a point in time. In this sentence, "labour till almost dark" means they work continuously until it becomes almost dark.
• This prepositional use is both grammatically and semantically accurate.

Grammatical rule used:
Use "till/until" to refer to time up to a specific limit.
Example: She studied till midnight.

Incorrect Options: · (b) utmost almost dark – “Utmost” is not a preposition and does not make sense here. (Hindi: "अत्यधिक")
· (c) by almost dark – “By” implies a deadline rather than continuous action. (Hindi: "तक")
· (d) still almost dark – “Still” means "up to now", which is incorrect in this time context. (Hindi: "अबतक")
