c the quotes provide credibility about the ups and downs of operating in the emergency response market.
d the quotes provide an opposing opinion on the field research used in rescue missions.

Explanation:

When an author uses quotations from an expert (in this case Clifford I. Nass), it is often to add credibility and provide specialized knowledge. Option B is correct as it aligns with the common use of expert quotes to offer insights. Option A is incorrect as there's no indication the quotes are about primitive technology limitations. Option C is wrong because the quotes are likely about the robots (as the context is rescue robots) not the emergency response market's ups and downs. Option D is incorrect as there's no mention of an opposing opinion about field research.

Answer:

B. The quotes provide expert insight on socially appropriate rescue robots.
