C Correct answer
Explanation

When a signed integer overflows (value exceeds maximum representable), it wraps around due to two's complement representation. The most significant bit (sign bit) flips, making the value negative. For example, if INT_MAX is 2147483647, adding 1 gives -2147483648 (INT_MIN). This is undefined behavior in C/C++ but typically results in wraparound.
