The term sum-of-products in boolean algebra means A. The AND function of several OR functions B. The OR function of several AND functions C. The OR function of several OR functions D. The AND function of several AND functions E. None of the above

The correct answer is: A. The AND function of several OR functions.

A sum-of-products is a Boolean expression that

is the OR of several AND terms. Each AND term is a product of several literals. For example, the expression $x_1 \lor x_2 \lor x_3$ is a sum-of-products, where the AND terms are $x_1 \land x_2$, $x_2 \land x_3$, and $x_3 \land x_1$.

The other options are incorrect. Option B is the definition of a product-of-sums. Option C is the definition of a disjunction. Option D is the definition of a conjunction. Option E is not a valid Boolean expression.
