Which word in the sentence is a preposition the young girl hid quietly and calmly under the table

a. under

b. young

c. and

d. quietly

The correct option is (A). According to grammarians, prepositions are non-lexical words since they do not carry meaning. However, in practice, prepositions carry meaning because it is not the same to say "the cat is under/behind/on/next to the table".

Option (b) is an adjective, option (c) is a conjunction and option (d) is an adverb of manner.
