Why answer is D why not B,  xy+wy = xy + yw Why considering them different?

@Praveen Saini Sir  @Anu007  xy+wy ,   xy + yw These two are different terms..?

No, in binary logic

Answer is D.See we can simplify each equation given in the option and get that all of them gives xy +wy. But let think in other way.

1st option is written in POS form, as we can check we get the same if we consider the following impicants.

which is (w+x)y

for second one

Which gives wy+xy

now for 3rd one we can verify like this

which is (w+x)(ˉw+y)(ˉx+y)

So as we can verify each equation in a given KMap, so answer is D

After simplification we get WY+XY
So Ans is Option D
