Let's analyze the code and the concept of indexing in C.

Code:

int main ()
{
    int xyz[8];
    return 0;
}

Explanation:

• int xyz[8]; declares an array xyz of 8 integers.
• In C, arrays are 0-indexed, meaning the indices start from 0 and go up to n-1 where n is the size of the array.

So, the valid indices for the array xyz with size 8 will be from 0 to 7.

Indexing:

• The first element will be at index 0.
• The last element will be at index 7.

Conclusion:

The correct indexing range for this array is 0 to 7.

Correct Answer:

(A) 0,7.
