To be fair, if someone asked me this question, I would get it wrong. Most likely, I'd ignore the question and answer something fairly random. If I did think about it, I'd probably start wondering if it was 364.25 days or 366.25 days until it takes me a couple of minutes to figure out those are sidereal days, and the revolution is in fact 365.25 normal solar days. I always have those two mixed up. I know that one of the two (rotation around the axis, and the revolution about the sun) is not what first comes to mind, but I never remember which.
