I think the answer is C) It prints: 2. The bit-shift operation `x<<2` effectively multiplies `x` by 4, so `fun(1)` returns 4, and when divided by 2, the result is 2.

The correct answer is B) It prints: 1. The function `fun(1)` returns 4, and when divided by 2, the result is 2.

I agree with Daniel, because the function fun() shifts the bits of the input left by 2 positions.
