Or you could look on it as an exercise in thinking logically to make up for the absense of some hard data. It's clearly not going to be 0% due to people not wanting to say things on record or just being too lazy to log in before they post. Taking a look at a few of the busier threads makes it pretty clear that most posts are by signed in users, so of the remainder there will be a mix between genuine ACs without an account and users who are not signed in. The brackets are pretty broad too, so 0-25% is almost certainly the correct answer.
Given the list of options, it's obvious that the values are to be rounded to a full multiple of 25%. So "0%" actually means "less than 12.5%" and "100%" means "more than 87.5%".
If the options were taken at exact value, it's practically guaranteed that none of the options fits. To start with, the 50% option being exactly true requires that the number of posts is even, therefore every second post it is guaranteed not to hold, and the 25% and 75% options can only hold if the number of posts is a multiple of four, that is, only once in four posts it is possible that one of them holds exactly.

Or you could assume the wording was wrong, and it obviously meant to be "How often you registered SN user post as AC?"
