Answer:
Instantiate the object and access the variable using object reference.
Explanation:
In order to use/access an instance variable in a class, the class needs to be instantiated.For example:
class Demo{
//Instance variable declaration
int testvar=0;
public static void main(String args[]){
//Class instantiation
Demo d = new Demo();
// The instance variable is accessed using the object reference
d.testvar = 1;
}
}
In case the instance variable in private then it can be accessed using its corresponding getter/setter methods.

D) A rendering engine displays content on the screen and a browser engine coordinates user interface interactions.
Explanation:
The rendering engine will deal with all the HTML code and will generate an output based on its own rules for interpreting the code. That's why different rendering engines will have different renditions of the same given HTML code. You can notice that in the acceptance of HTML5 and CSS3 tags, which are not universal yet.
The browser engine will deal with the user interface and all other features that make a browser a browser, relying on the rendering engine for the display.
That duality allows different browsers to use the same rendering engine, thus have similar outputs.
