Q. What is the result of compiling and running the following code?

public class Tester{
	static int x = 4;
	int y = 9;  	
	public Tester(){
		System.out.print(this.x); // line 1
		printVariables();
	}
	public static void printVariables(){
		System.out.print(x); // line 2
		System.out.print(y); // line 3
	}
	public static void main(String... args) { // line 4
		new Tester();
	}
}

• (A) Compile error at line 1 (static x must be only accessed inside static methods)
• (B) Compile error at line 3 (static methods can't make reference to non-static variables)
• (C) Compile error at line 4 (invalid argument type for method main)
• (D) 49
