Answer: (C)
Explanation:

Note that the sizeof() operator would return size of array. To get size of string stored in array, we need to use strlen(). The following program prints 9. 

#include <stdio.h>
#include <string.h>
int main()
{
    char str[20] = \"GeeksQuiz\";
    printf (\"%d\", strlen(str));
    return 0;
}
