Best answer
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.???
