Which logical operator checks for a condition being true or false?

The logical operator that checks for a condition being true or false is indeed the "iif" function. This function stands for "immediate if" and is commonly used in programming and query languages to evaluate a single condition. It takes three parameters: a condition to evaluate, the result if the condition is true, and the result if the condition is false. This means that "iif" effectively checks the truth value of a condition and provides a way to branch logic depending on that evaluation.

The other options serve different purposes. The "AND" operator combines two conditions and returns true only if both conditions are true, while the "OR" operator returns true if at least one of the conditions is true. The "CASE" statement, on the other hand, evaluates multiple conditions sequentially and returns the result corresponding to the first true condition. While all these options are associated with logical evaluations, "iif" distinctly functions to assess a single condition and return outcomes based on its truthiness.
