The critical point of a hexadecimal number can be found by converting it to binary and looking for the first bit after the hexadecimal point that is a 1. In this case, the binary representation is 0001 0001 1110 1101 0000 1000 1011 1100 1110 1111 1011 1000 1010 0000 0000 0111 0010 0100 0101 1101 1110 1111 1011 1000, and the first bit after the hexadecimal point that is a 1 is the first bit, which corresponds to a value of 1/16. This corresponds to the point (0,0) in decimal coordinates, so the answer is D.
