### Understanding Method Calls in Java In the main function below, what do we call the type of statement shown on the line with the comment? ```java public static void main(String[] args) { Cat whiskers = new Cat(); whiskers.meow(); // THIS LINE } ``` 1. ○ A method call 2. ○ A method definition 3. ○ A constructor 4. ○ A member assignment #### Explanation: - **Context:** The code snippet is a part of a Java program where a `Cat` object named `whiskers` is created. The line marked with the comment `// THIS LINE` is worth focusing on. - **Identification:** This line calls the `meow` method on the `whiskers` object. - **Terminology:** - **Method Call:** Refers to executing a method (function) that belongs to an object or class. Here, `whiskers.meow()` is invoking the `meow` method. Answer: The correct choice is "A method call."
