From Fig.(e),
A.B.(C.D' + E.F)
= A.B.C.D' + A.B.E.F
Fig (a) is excluded as AND gate has 6 inputs,
Fig (b) is excluded as it is the product of the sums,
Fig (c) is excluded as OR gate has 3 AND inputs,
So,
Fig (d) is the correct answer as it is the sum of products.
A.B.(C.D' + E.F)
= A.B.C.D' + A.B.E.F
Fig (a) is excluded as AND gate has 6 inputs,
Fig (b) is excluded as it is the product of the sums,
Fig (c) is excluded as OR gate has 3 AND inputs,
So,
Fig (d) is the correct answer as it is the sum of products.

The option d is correct.

Here, at d option contain the OR gate followed by the AND gates so SOP form.

Since we get output of e ckt as (c*^d+e*f)*a.b multiply we get abc^d+abef which sum of product form.

A.B.C.^D + A.B.E.F IS THE SUM OF PRODUCT
