i have a question for mux4way16 gate.

 * out = a if sel == 00
 *       b if sel == 01
 *       c if sel == 10
 *       d if sel == 11

i have this, but it is wrong

//deleted

but the correct answer is

//deleted

this confused me, my idea is to filter ab or cd based on first bit sel[0].
and filter the answer based on second bit sel[1]
