PM: Building materials meet the safety codes but pose some safety risk. Since we have developed a technology to make a safer version, we should only sell a safer version and discontinue the current one.
SM: If we stop selling the current product, we will have no money to develop and promote the safer product. We need to continue to sell the current product to marker the safer product successfully.
SM counters the PM argument by.
Let's look at the answer choices:
(A) is the correct answer choice because in his response SM points out that that stopping production of the current product (one part of his proposal) would prevent the company from successfully developing and marketing the safer product (the other part of his proposal).
(B) is irrelevant. SM never challenges PM's authority.
(C) is irrelevant. PM never assumes that the product is safe, just that it is safer than the current version.
(D) is irrelevant. SM never proposes changing the safety standards, he merely questions PM's plan for switching to a safer product.
(E) is irrelevant. SM never presents any new evidence, he merely makes an argument to demonstrate the issue with the PM's proposal.
