see for g0 , g1 ,g2 ,g3 are separate functions of h(x) in themselves..its like the same thing designing one flip flop from other kind
if we need to find g0 see where it is 1 for h(x)
like it is one at row no 0,1,4,5,8,9,12,13..these are row nos not min terms...so for those rows find out the min terms and represent...like see row 0..min term there is 0...see row 1 min term is 1...now see row 4 min term is 0110 means 6 and so on...do this for all and then match with options.
