In Scratch, where would you find the "When Clicked" block?

1. Control

2. Events

3. Actions

4. Sensors

The correct answer is: Events

The "When Clicked" block is found under the Events category in Scratch. This block is designed to initiate a script whenever an object (sprite) is clicked with the mouse. It is a key part of the interactive capabilities of Scratch, allowing users to create games and animations that respond to user input. Events in Scratch are fundamental because they help manage the execution of scripts based on user actions or internal triggers. By placing the "When Clicked" block at the start of a script, developers can effectively control how the sprite behaves, making it essential for creating engaging and interactive experiences. Although other categories like Control, Actions, and Sensors contain important blocks as well, they serve different purposes. Control blocks focus on the flow of scripts (like loops and conditional statements), Actions typically pertain to performing tasks (such as moving the sprite), and Sensors deal with detecting conditions or states. The Events category specifically triggers actions based on interactive events, which is why the "When Clicked" block is appropriately classified there.
