On the other hand, since we know nothing about Anne other than the fact she’s looking at George, one might argue that Anne may not be a person, and conclude that we have insufficient information to determine the answer.

You have to assume that a person has two states, married or unmarried. Widowed and divorced are ignored.

Conjecture: Opinion or judgment based on inconclusive or incomplete evidence; guesswork.
I guess if Mary is married, the answer is “A”
I guess if Mary is unmarried, the answer is “B”
Otherwise, with the details provided, even if she were wearing a wedding band, the answer is “C”
