C Correct answer
Explanation

Robert and Scott each say 'One of the other two stole it. I did not do it.' Tommy says the same thing but we know he's lying. If Tommy is lying, then his statement 'One of the other two stole it AND I did not do it' is false. This means it's NOT the case that someone else stole it while Tommy is innocent. Since there's only one thief, this implies Tommy himself is the thief. If Tommy stole it, then Robert and Scott are telling the truth when they say 'I did not do it' (they didn't) and 'one of the other two' (Tommy) stole it.

AI explanation

To solve this question, we need to analyze the statements given by the suspects and determine who is telling the truth.

Let's go through each statement:

Robert: "One of the other two stole it. I did not do it." Scott: "One of the other two stole it. I did not do it." Tommy: "One of the other two stole it. I did not do it."

From their statements, we can conclude that each suspect is blaming the other two and claiming their own innocence. However, since the police later found out that Tommy was lying and there was only one thief, we can conclude that Tommy is the thief.

Therefore, the correct answer is C. Tommy.
