The decoder is a combinational circuit that has 'n' input lines and maximum of 2^n output lines.
So, 1-of-10 BCD decoder has n=4 inputs; 2^4 = 16 output lines.
1 Extra line that is for ENABLE signal which is normally active low.

1 select line,
3 inputs- 000-11, 12, 13-0 to 9.
3 inputs- 000-11, 12, 13-0 to 9.

We can make 1 of 10 decoder with 4 inputs Because the inputs are b1, b2, b3, b4 and outputs extends to d0 to d9.

A is correct because 1-of-10 stands for BCD to decimal decoder.
