Which operator must evaluate all conditions to true for an action to be performed?

The AND operator is used in logical expressions where all conditions must be true for the result to be true. This means that if any one of the conditions connected by the AND operator is false, the entire expression will evaluate to false, and the action will not be performed.

For instance, consider an example where a user must meet multiple criteria to qualify for an action, such as having a certain age and holding a valid driver's license. In this case, both conditions need to be satisfied for the action to take place; if one condition is not met, the outcome is negative.

In contrast, the OR operator requires only one of the conditions to be true for the action to be executed. The NOT operator negates the condition, and the XOR operator requires exactly one of the two conditions to be true, but not both. Thus, the structure and function of the AND operator are what make it necessary for all conditions to be true for an action to be performed.
