Answer 2

In this sentence, a word is missing which can make the word meaningful and grammatically correct.

If we check here is a preposition is missing.

So to complete the sentence and make it correct you have to write it like, Man’s efficiency increases by hard work.

Sometimes students use with or to but by is the right answer.
