can you help me to solve this question by using "C" language

this four images are just a one question. help me as soon as possible.

Multiplexers and De-Multiplexers Multiplexer is a combinational circuit that has maximum of 2n data inputs, n selection lines and single output line. One of these data inputs will be connected to the output based on the values of selection lines. - Since there are n selection lines, there will be 2n possible combinations of zeros and ones. So, each combination will select only one data input. Multiplexer is also called as Mux. Multiplexers and De-Multiplexers 4x1 Multiplexer - 4x1 Multiplexer has four data inputs 13, 12, 1; & Io, two selection lines Si & So and one output Y. The block diagram of 4x1 Multiplexer is shown in the following diagram. 13 I2 4x1 Multiplexer I 1 1 1 S1 so O Multiplexers and De-Multiplexers One of these 4 inputs will be connected to the output based on the combination of inputs present at these two selection lines. Truth table of 4x1 Multiplexer is shown below. Selection Lines Output S1 So Y 0 0 lo 0 1 11 1 0 12 1 1 13 Multiplexers and De-Multiplexers S1 From Truth table, we can directly write the Boolean function for output, Y as SO 13 Y = S' SO'I + S_'SQ11 + SIS,'I + S S 12 + 12 D 11 10
