 [A]. (A + B)(C + D) [B]. (A)B(CD) [C]. AB(CD) [D]. AB + CD

Explanation:

No answer description available for this question.

 Vinay Kumar said: (Aug 24, 2011) What is SOP?

 Pallabi said: (Nov 15, 2011) SOP stands for sum of products form. here in AB+CD the expression is the sum of two products AB and CD.

 Kingshuk said: (Sep 5, 2012) SOP is sum of minterms.here no of variable=4(A,B,C,D) so AB+CD is not a SOP form.for example ABCD+ABCD' is a SOP form.which can be written as sum(14,15).because 14=1110; and 15=1111 in binary which makes the corresponding minterm logic high.

 Jeevan said: (Sep 6, 2013) Sop means the sum of product for example ab+cd is nothing but a and b are products, c and d are products so the curect answer is ab+cd.

 Rohit Soyal said: (Nov 20, 2013) SOP means the sum of product for example DE+EF.

 Iita Andreas said: (May 8, 2015) The answer is D, because AB+CD is the sum of two fundamental products and none of the two is included in the other fundamental product.

 Kamal Raz said: (Jul 23, 2015) Product means a variable, sum means addition. So, two product AB & CD are summed.

 Rishika Kumari said: (May 16, 2016) SOP stands for Sum of Product. AB + CD are the two fundamental product.

 Jino Antony said: (Aug 9, 2017) How to describe the answer?

 Senudi said: (Aug 24, 2019) What is a minterm?

 P.Vamsiteja said: (Oct 22, 2020) Minterm (plural minterms): In Boolean algebra, a product term, with a value of 1, in which each variable appears once (in either its complemented or uncomplemented form, so that the value of the product term becomes 1).
