Fill in the blank with the most appropriate word.The boss made him ____ the report all from the beginning.

Answer: Option A

The verb “make” in the causative form is followed by the base form of the verb (bare infinitive).

Example: She made him clean the room. (not cleaned, not cleans)

Therefore, after “made him,” the correct form is the base verb “write.”

So, the correct sentence is:

The boss made him write the report all from the beginning.
