Answer:
(A) At least some volunteers who said they had acted fairly in choosing the easy task would have said that it was unfair for someone else to do so.
Step-by-step explanation:
Option A is correct because it portrays a situation whereby the people in the initial group had opposing answers when the condition changes against them.
Option B is incorrect because the issue of moral choice is not what is being considered but rather moral standards
Option C is incorrect because for the argument to be valid, the same people that gave the initial judgment should be able to change their judgment given different condition. Not just random people.
Option D is incorrect because for the argument to be valid, it does not require whether the other group is accurate in their judgment or not.
Option E is also not correct because there is nothing to compare their conclusion of saying their choice was fair. Any group could just say that, there nothing in the statement to prove otherwise.
