One advantage of binary code over hexadecimal code is that D. it is read and understood more easily by computers.
Binary code consists of only two symbols, 0 and 1, which can be easily interpreted by electronic devices, including computers. On the other hand, hexadecimal code uses 16 different symbols (0-9 and A-F) to represent numbers, which requires more processing power to convert and interpret. While hexadecimal code is easier for humans to read and write than binary code, it is less efficient for computers to use.
