The IEEE/ANSI symbol for a decoder has the internal designation BCD/DEC. This means the decoder is a:
A) binary coded decimal to decimal decoder with ten inputs and four outputs.
B) binary coded decimal to decimal decoder with four inputs and ten outputs.
C) decimal to binary coded decimal decoder with ten inputs and four outputs.
D) decimal to binary coded decimal decoder with four inputs and ten outputs.

A BCD/DEC decoder is designed to convert Binary Coded Decimal (BCD) inputs into decimal outputs. BCD uses 4 bits to represent the ten decimal digits (0 to 9), so the decoder has four inputs (for the BCD) and ten outputs (one for each of the ten possible decimal digits).
