Answer:
c.We had to establish guidelines for the acceptance of used computing equipment because only new computers provide warranties, compatible software, and come with matching peripherals.
Step-by-step explanation:
An indirect message aims to soften bad news, to achieve this goal the message is transmitted through a soothing speech, where there is an explanation of the reasons for the bad news before reaching the fact, in order to cushion the impact that the message may cause. Indirect discourse is more accepted in the case of the transmission of bad news, as individuals generally tend to better understand the facts when they are explained through evidence.
Therefore, the letter c corresponds more adequately to an indirect speech.
