In boolean algebra, the times sign stands for the _____ operation A. AND B. OR C. NAND D. NOR E. None of the above

The correct answer is: A. AND

In Boolean algebra, the times

sign ( $\times$) stands for the AND operation. The AND operation is a binary operation that takes two operands, $A$ and $B$, and returns a value of 1 if both operands are 1, and a value of 0 otherwise.

The OR operation is a binary operation that takes two operands, $A$ and $B$, and returns a value of 1 if either operand is 1, and a value of 0 otherwise.

The NAND operation is a unary operation that takes one operand, $A$, and returns a value of 0 if $A$ is 1, and a value of 1 otherwise.

The NOR operation is

a unary operation that takes one operand, $A$, and returns a value of 1 if $A$ is 0, and a value of 0 otherwise.
