When performing BCD addition, what is the maximum value that can be represented in a single BCD digit?

Correct Answer (Detailed Explanation is Below)

E. None of the above

Detailed Explanation

Explanation:

In Binary Coded Decimal (BCD), each decimal digit (0–9) is represented using 4 binary bits.

Possible 4-bit combinations:

• Binary range: 0000 (0) to 1111 (15)

• But in BCD only decimal digits 0–9 are valid

So the valid BCD values are:

Values 1010–1111 (10–15) are invalid in BCD.

✅ Therefore, the maximum value represented in a single BCD digit is 9.

Since 9 is not in the options, the correct choice is:

(E) None of the abov
