C Correct answer
Explanation

This is the correct answer. Substring method takes two parameters (BeginIndex, EndIndex).Substring(int Begin, int End). It returns the string from the beginning to end – 1. But if the BeginIndex is equal to the EndIndex, then an empty String with length 0 will be returned. So, here substring(4, 4) will return an empty string of length 0.
