SOP stands for sum of products form.
here in AB+CD the expression is the sum of two products AB and CD.

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.

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.

SOP means the sum of product for example DE+EF.

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.

Product means a variable, sum means addition. So, two product AB & CD are summed.

SOP stands for Sum of Product.

AB + CD are the two fundamental product.

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).
