Consider the following code snippet:

if (e.getButton() == MouseButton.PRIMARY) {
circlePane.enlarge();
}

Which mouse button represents this circle enlangement action?

a). Left Button

b). Right Button

c). Middle Button

d). None of the above

Assume the following lambda expression:

btEnlarge.setOnAction(e -> circlePane.enlarge());

The above line means that onclicking the button objecte (btEnlarge), circlePane (containing a circle) will increase the radius.

True or False?
