Which value does the block return when a sprite is not touching the selected object?

1. 0

2. NULL

3. True

4. False

The correct answer is: False

The block returns False when a sprite is not touching the selected object because this behavior is designed to indicate a binary state—whether the sprite is currently in contact with the object or not. When the condition being checked is that a sprite is not in contact with the object, the logical outcome is False, representing the absence of contact. In many programming environments, a touch detection mechanism will output True if two objects are colliding and False if they are not. This makes it easy for programmers to implement logic based on whether sprites overlap or interact in a certain way. Thus, when a sprite is not touching the selected object, the appropriate return value to signify this condition is indeed False.
