In binary, each digit can represent 2^n, where n is the position of the digit from right to left, starting from 0. Therefore, for 1111, we have:
1 * 2^3 + 1 * 2^2 + 1 * 2^1 + 1 * 2^0 = 8 + 4 + 2 + 1 = 15
In hexadecimal, each digit can represent 16^n, where n is the position of the digit from right to left, starting from 0. The largest digit in hexadecimal is F, which represents 15 (since we count 0 as the first digit). Therefore, 1111 in binary corresponds to D in hexadecimal, which represents 13 in decimal. 
However, the question is asking for the hexadecimal equivalent of 1111 in binary, which is 15, and is represented by the digit D in hexadecimal. Therefore, the correct answer is D.
