Answer – C. 4

The answer to the question, ‘how many bits are needed to store one BCD digit’ is 4.


Binary Coded Decimal is abbreviated as BCD. So, here we will use the code in the binary (unsigned) form only but for representing the digits of the decimal number system. In the decimal number system, the maximum value that we can represent for a single digit is nine. For representing this number, we require four bits in the BCD code. Hence, by using four bits we can represent any of the decimal digits ranging from zero to eight. Therefore, Option (C) is the correct answer.
