Attempted by 76 students.
Show answer & explanation
Correct answer: B
The correct option is B. BCD (Binary Coded Decimal) is a weighted code where each bit position has a fixed mathematical weight, specifically 8, 4, 2, and 1. Conversely, Excess-3 and Gray codes are non-weighted codes because their bit positions do not carry specific positional weights.
