First, there’s no mention of size of pay adjustment here. Second, sure, your point is valid, but in the context of this post, let’s not be ridiculous. This is a multiple-choice question, so sometimes you need to rank options and choose the best. No same person is more likely to stay at a company because of a ping-pong table in lieu of a better salary. Now if they’d said

An employee appreciation program, which includes such things as free meals and a recreation room with a ping pong table

that would be a different story. But as-is, it’s ridiculous.
