He hardly works.

strenuously
scarcely
mostly
arduously

The correct answer is B. scarcely.

Scarcely means “almost not at all.” It is an adverb that describes how much or how often something happens. In the sentence “He hardly works,” scarcely means that the person does not work very much.

The other options are incorrect because they do not mean “almost not at all.”

  • Strenuously means “with great effort.”
  • Mostly means “for the most part.”
  • Arduously means “with great difficulty.”
