answer is C)
Total programmable fuses= fuses required by AND gates + fuses required by OR gates
(Fuses are attached to and- or gate inputs to allow inputs to reach the and - or gates and If fuses don't work , then no input can reach to these gates of PLA)
Fuses required by AND gates = 2* no. Of inputs * no. Of and gates = 2*16*32= 1024 fuses
Fuses required by OR gates = no. Of outputs * no. Of and gates = 8* 32 = 256 ( total outputs should be equal to no. Of OR gates and inputs have to cross AND gates and then goto OR gates)
Total fuses = 1024+ 256= 1280
