Answer:

A decoder is a combinational circuit that converts binary information from 'n' input lines to a maximum of 2^n unique output lines. The number of output lines for a decoder with 'n' input lines can be calculated using the formula 2^n.

In this case, we are given that the decoder has 4 input lines. So, the number of output lines can be calculated as 2^4, which is equal to 16.

Explanation:

A decoder is a digital circuit that takes binary inputs and produces a unique output line for each possible combination of input values. The number of input lines in a decoder determines the number of unique combinations it can represent.

In general, a decoder with 'n' input lines can represent 2^n unique combinations. This is because each input line can have two possible values, either 0 or 1. So, for 'n' input lines, there are 2^n possible combinations.

In this case, the decoder has 4 input lines. So, the number of unique combinations it can represent is 2^4, which is equal to 16. Therefore, the number of output lines for this decoder is 16.

Conclusion:

The correct answer is option 'B', which represents 16 output lines for a decoder with 4 input lines.
