Answer 1

The correct option is B more diligently

The given sentence is an example of the adverb of comparative degree. An adverb that compares two things becomes a comparative degree of an adverb. 'Diligently' is an adverb of positive degree. 'More diligently' is a comparative form of degree. 'Most diligently' is the superlative form of an adverb. 'Diligent' is an adjective.

Thus, option B is the correct answer out of all the options.
