Choose the appropriate Assertive sentence for the following sentence:

What a piece of work is Man!

Man is a wonderful piece of work.

The correct answer is Option (1) - Man is a wonderful piece of work.

The given sentence:

"What a piece of work is Man!"

is an exclamatory sentence expressing wonder or admiration. We are asked to convert it into an assertive sentence (a statement that declares or affirms something without emotion).

This exclamatory sentence emphasizes the wonderful and admirable nature of Man.
It can be rephrased without the exclamation and in the tone of a factual statement as:

"Man is a wonderful piece of work."

This keeps the original meaning and admiration intact while converting it into an assertive form.
