The correct answer is: A. write
The boss made him write the report all from the beginning.
The verb “write” is used to describe the action of putting words on paper or a computer screen. It can be used in the present tense, past tense, or future tense. In this case, the boss is telling the employee to write the report right now, so the present tense is correct.
The other options are incorrect because they are not in the present tense. The verb “written” is the past participle of the verb “write,” and it is used to form the perfect tenses. The verb “wrote” is the simple past tense of the verb “write,” and it is used to describe actions that happened in the past. The verb “writes” is the present tense of the verb “write,” but it is not used in this context because the boss is telling the employee to write the report right now, not in the future.
