Correct Answer (Detailed Explanation is Below)
C.
8
Detailed Explanation
Correct Answer: 8
The pointer p initially points to a[1], whose value is 4.
Pointer indexing follows the same rule as array indexing. Therefore, p[2] is equivalent to *(p+2).
Starting from a[1], moving two positions reaches a[3], whose value is 8.
Therefore, the output is 8.
