Decoder is one to many.

Encoder is many to one.

How it is possible?

Encoder :- encoder converts an active input signal into a coded output signal
Decoder :- decoder converts the coded input signal into an active output signal.
So, Decoder is correct answer

The decoder has two possibilities.

1) For 'n' inputs it produces 2^n outputs and.
2) It converts encoded (binary) input into human understandable or as an active signal.
