Show answer & explanation
Correct answer: B
Explanation: A decoder is a combinational circuit that converts coded inputs into a set of outputs where each unique input code activates a distinct output pattern. A BCD-to-seven-segment decoder specifically translates a 4-bit Binary-Coded Decimal (BCD) input into seven outputs (a, b, c, d, e, f, g) that drive the segments of a seven-segment display to show decimal digits 0–9. Inputs: four BCD inputs (A, B, C, D) representing binary codes for decimal 0–9.
