p) God can lift all stones.
q) God can create a stone he cannot lift.
The question "p AND q ?" leads to a direct logical contradiction.
However, the question that Tim posed is selfreferential, meaning you can not construct a logical statement that can be proven in a mathematical framework that is both complete and consistent, as per Gödel's incompleteness theorems.
[edit]
tl;dr: Paul's question has a definite answer: "no". Any answer to Tim's question can not be proven.

No. If there are two correct answers among four possible answers, statistically you'll have 50% chance to randomly pick the right one. The question here is, how many correct answers are there? Any answer to that question is improvable.
Refer to Russell's Paradox.

That's not how statistics works. It doesn't imply there is one correct answer. There could be multiple correct answers. There could be no correct answer. What if the four possible answers were:
a) 100%
b) 100%
c) 100%
d) 100%
If you picked one at random and followed your logic, your answer would still be 25%, even though statistically you have 100% change of randomly picking the correct answer. Statistics deals with information you know A Priori. If the possible answers in the original question were whited out, you would be correct to say 25%. However, you know the possible answers A Priori, so you have to factor that into your statistical analysis.

Here's where the issue lies. From what do you deduce that there's exactly one correct option among the four given options?
