What structure performs a function if an argument is true?

• A. while
• B. if
• C. for
• D. elif

Answer: (B)

The structure that performs a function if an argument is true is the "if" statement. In Python programming, the "if" statement is fundamental for decision-making, allowing the code to execute a specific block only when the provided condition evaluates to true. For example: ```python if condition: # Code to execute if condition is true ``` When the condition specified after the "if" evaluates to true, the code indented under it runs. If the condition is false, the code inside the "if" block is skipped, and the program continues to the next part of the code or to any other conditional statements, if present. This structure is crucial for implementing logic that requires certain actions to occur based on specific criteria. In contrast, the other options represent different control structures. The "while" loop repeatedly executes a block of code as long as a specified condition remains true but does not directly execute based on a single conditional argument being true. The "for" loop is used for iterating over a sequence (like a list or a range), and "elif" is a conditional structure that follows an "if" statement to check another condition if the previous "if" was false. Thus, the "if" statement
