What are boolean values in programming?

True and false values used in conditions Numbers used for counting Strings that describe data Lists that store multiple items

Correct Answer:

True and false values used in conditions

Explanation:

Boolean values are true or false, and they’re what let programs make decisions. When you test a condition in an if statement or a loop, the result is either true (the condition is met) or false (it isn’t). Those true/false results come from comparisons like 5 > 3 or 2 == 2, and from combining statements with and, or, and not. This true/false information tells the program which path to take or whether to keep repeating a block. Booleans are a distinct type in many languages, separate from numbers or text, though some languages also treat other values as true or false in a broader sense (truthy or falsy).
