Try this idea:

if you want to select in0 when select = 0000 then it means:

select-------in0-------out

0000---------0-------0

0000---------1-------1

hence for nand gate invert all select lines and output and you get:

select--------in0--------nand out inverted

1111----------0---------0

1111----------1---------1

for in1 when select = 0001 invert the first 3 lines and so on
