Choose the sentence in which the given word is used correctly (grammatically and semantically). Word: ALMOST
Almost means "very close to, but not quite" and it works as an adverb that must sit right before the word or phrase it is modifying, usually the verb whose action almost happened. Here that verb is "hit", so "almost" should sit directly before "hit" and the sentence should make clear that the collision was narrowly avoided.
Only option A places "almost" correctly, right before the verb "hit", and keeps the meaning clear and unambiguous: the speaker was crossing the road and a scooterist very nearly hit them.
Let's summarize:
The grammatically and semantically correct sentence is option A.
