βœ… Correct Answer: (D) s

Explanation: The crux of the program lies in the expression: 5["GeeksQuiz"] This expression is broken down by the compiler as: *(5 + "GeeksQuiz"). Adding 5 to the base address of the string increments the pointer(lets say a pointer was pointing to the start(G) of the string initially) to point to Q. Applying value-of operator gives the character at the location pointed to by the pointer i.e. Q.
