Here are my thoughts on this question:
The principle cites that there are two conditions that MUST be met (only if) that justifies one to criticize the works of another person:
1) won't seriously harm the person criticized
2) one does so in the hope/expectation of benefiting someone other than oneself
So, if either of these conditions is not met, then by the contrapositive, the principle asserts that one should not criticize the works/actions of another person.
In the application, the claim is that Jarret should not have critized Osterag's works. However, the premise that it uses sollowing since doesn't by itself justify this claim using the principle. In the application, all we know is that the defects benefited noone. In the principle, for condition 2 to hold, it's based on the "hope/expectation."
So it would be possible, for example, that Jarrett hoped the defects would benefit someone else, even though they were actually so obvious that noone ended up benefitied.
A is correct because it shows that condition 2 of the principle (a necessary condition) is not met because he knew they would not benefit anyone (so obviously it wasn't possible that he hoped/expected the criticism to benefit someone). Hence by the contrapositive the application's claim can be made.
Answer choice B is incorrect because it does not touch on either of the necessary conditions that are asserted by the principle.
I'm thinking maybe you thought that by the contrapositive of B, we can show that the criticism did not benefit Osterag. If this is the case, then it still doesn't justify the principle, for the following two reasons: 1) the first necessary condition requires that it seriously harms the person, which is different from not being to someon's benefit 2) we can't deduce from the info following "since" in the application that Osterag was unaware of the defects.
