The salesperson in medication ads dresses to look like a doctor because:

a. she has tested the product directly.

b. the product was developed by physicians.

c. FCC regulations demand this.

d. the salesperson's credibility is enhanced.

I think it is b but I also thought a might be right.

Neither a nor b is correct.

It's just an actor who is trying to sell you medication.

So would it probably be d?

Yes, it's d.

To determine the correct answer, let's evaluate each option:

a. she has tested the product directly: This option suggests that the salesperson dresses like a doctor because she personally tested the product. However, this is not necessarily the reason for the attire.

b. the product was developed by physicians: This option suggests that the salesperson dresses like a doctor because the product was developed by physicians. This aligns with the common marketing strategy of associating medical expertise with the product, so it could be a plausible answer.

c. FCC regulations demand this: The Federal Communications Commission (FCC) primarily regulates the broadcasting industry, not the clothing choices of salespeople in medication ads. Thus, it is unlikely to be the correct answer.

d. the salesperson's credibility is enhanced: This option suggests that the salesperson dresses like a doctor to enhance their credibility. This aligns with the idea of associating a professional appearance with trustworthiness, so it could also be a plausible answer.

Based on the explanations, both option b (the product was developed by physicians) and option d (the salesperson's credibility is enhanced) seem reasonable. However, without further context or specific information from the source providing the question, it is difficult to definitively determine the correct answer.
