I have a question as to why answer choice B is not the correct answers.
On lines 30-34, the author states that "the CEO (of a non charitable organization) SHOULD still work to maximize profits, because that will turn out best..."
Answer choice B says SHOULD make decisions; whereas A says are OBLIGATED. The economists' clearly state that they believe these CEO's should maximize profits, the economists don't make a claim as to whether or not it is obligatory.
Any help?
