Answer:
C. He should include specific details and dollar amounts.
Explanation:
The main issue that the passage talks about is the case of 'unreliability' that the co-workers think of Anwar. They do not trust him with the report he gave. And they also believe that he is lying about the expenses that he's reported. So, for Anwar to prove his point and to show that he is actually giving the truth in his reports, he should include the specific details of the expenditure along with the amounts of dollars spend in each and every way. This production will enable others to see where exactly the money went and will be sure to understand and know the true expenditure of the company.
Thus, the correct answer is option C.
