What does the NOT (!) logical operator do to its boolean argument?

Inverts the value
Sets it to false
Increments the value
Decreases the value

The correct answer is: Inverts the value

The NOT logical operator inverses the boolean value of its argument. This means that if the argument is true, the result will be false, and vice versa. Options B, C, and D are incorrect because they do not involve inverting the value of the boolean argument. Setting it to false, incrementing or decreasing the value are all different operations that do not result in inversion.
