BCD (Binary-Coded Decimal) represents each decimal digit separately using a 4-bit binary number.
Example:.
Decimal 59 in BCD is:.
5 → 0101.
9 → 1001.
So, 59 = 0101 1001 in BCD.
A 4-bit code is used because 4 bits can represent values from 0 to 15, which is enough to store decimal digits 0–9.
Only the binary combinations from 0000 to 1001 are used in BCD.
Hence, the correct answer is: 4-bit binary code.
