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 another way.

$1^{st}$ option is written in $POS$ form, as we can check we get the same if we consider the following implicants.

which is $(w+x)y$

for the second one

Which gives $wy+xy$

 

now for 3rd one, we can verify like this

which is $(w+x)(\bar w+y)(\bar x+y)$

So as we can verify each equation in a given K-Map, so the answer is option D
