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.
