With 8-bit codes, there can be a maximum of 256 different symbols (2^8 = 256). However, not all of these symbols have to be alphabetic, so the number of alphabetic symbols can be less than the maximum of 256. Therefore, the best choice is D, which states that the number of alphabetic symbols must be less than 256.
