1. $(w+x)y$
2. $xy + yw$
3. $(w+x) (\bar w + y) (\bar x + y)$
4. All of the above implement the given Karnaugh Map

@Bikram @Arjun @Shaik Masthan  Pls tell me how (c) is also coming as POS, I am only getting (a) and (b) as the asnwer.

try to represent option C in K-map, then you will understood how C is also derived.

Sum of Product = xy+yx
Product of Sum = (w+x)(w¯+y)(x¯+y)

Option A and B are Sum of Product and option C is Product of Sum.
Answer should be none of these.

why have we combined the terms for pos as shown above.

Why not combine the 1st row of zeros with the last row of zeros to make a subcube of size 8 , thereby eliminating 3 variables.???

@Digvijay Pandey Are u sure that is the correct POS?? I am getting (y')(x' + w')

how yo got product of sum as option c in this question sir
