No. From: "Jack is looking at Anne, and Anne is looking at George. Jack is married and George is not. Is there a married person looking at an unmarried person?"
Jackm --> AnneM? UM?
AnneM? UM? --> GeorgeUM
The options are:
a) Yes b) No c) Can't tell from the given information
We have no idea from this info whether Anne is married or unmarried. However, these are the only two cases.
Case 1: If Anne is married, then Anne (married) is looking at George (unmarried)
Case 2: If Anne is unmarried, then Jack (married) is looking at Anne (unmarried)
So yes, the answer is (now) obviously a) Yes: A married person is looking at an unmarried person.
Most people get hung up on the fact that they cannot tell whether it's Jack --> Anne or Anne --> George, and say, "indeterminant," when the question isn't asking who's married or unmarried, it's asking whether "a married person" (doesn't matter who) is looking at an unmarried person (also doesn't matter who).
