I got this problem from one of the mock exams. Is it ok to access static members using the this reference?

Q. 17
What is the result of compiling and running the following code:
public class Test {
static int total = 10;
public static void main (String args []) {
new Test();
}
public Test () {
System.out.println("In test");
System.out.println(this);
int temp = this.total;
if (temp > 5) {
System.out.println(temp);
}
}
}
A. The class will not compile
B. The compiler reports and error at line 2
C. The compiler reports an error at line 9
D. The value 10 is one of the elements printed to the standard output
E. The class compiles but generates a runtime error
Answer is D.
