A 4x1 multiplexer has four 2-input AND gates and one 3-input OR gate.

Here's why:

1. A 4x1 multiplexer has 4 input lines, 2 selection lines, and 1 output line. The 4 input lines are connected to the 2-input AND gates.

2. The 2 selection lines are used to select which input to forward to the output. If we have 4 inputs, we need 2 selection lines (since 2^2 = 4).

3. The outputs of the AND gates are connected to a 3-input OR gate. The OR gate is used to forward the selected input to the output line.

So, the correct options are "It has four 2 – input AND gates" and "It has one 3 – input OR gate".
