Answer
The correct answer is option(C) which is "Index".
Explanation:
Array elements can be differentiated because each element in the array have different index value.In the array all elements are of same data type, so we can not differentiated them on the basis of data type. Also an array can have same value many times, That is why we can not differentiated them on this basis. In the array elements are from any range, so its not possible to distinguish them on range. We can only distinguish elements of an array on their index value because each element have different index in the array.
