Show answer & explanation
Correct answer: D
Binary Coded Decimal (BCD) only uses ten valid states from 0000 to 1001 (decimal 0–9). When mapping BCD to a 4-variable K-map, the remaining six states from 1010 to 1111 (10–15) are restricted, invalid combinations treated as "Don't Care" conditions. Thus, option D is correct.
