Need help pls public class TestThread extends Thread { private static int x;
public synchronized void doSomething () {
int current = x;
current++;
x = current;
}
public void run() {
doSomething();
}
}

Which statement is
true?
Select one:

a. Declaring the doSomething() method as static would make the class thread-safe

b. Synchronizing the run() method would make the class thread-safe

C. The data in variable "X" are protected from concurrent access problems

d. Compilation fails
e. An exception is thrown at runtime
