Answer 1

Answer :

Preposition

Prepositions are words that join a noun, a pronoun or a group of words acting as a noun with another part of a sentence. A preposition should always have at least one object (noun, pronoun or a group of words acting as a noun). This is the object that it joins with the rest of the sentence.

Now answer will be C) By

Rule of By "

'By' is a preposition that expresses proximity(by the riverside), means(come by train), action with a purpose( passed by working hard), a person's action in passive voice( done by him). 'It is ten o'clock by my watch' expresses that according to my watch, the time is ten o'clock.
