Choose the correct statement in context of the following program code.public class Test{ public static void main(String[] args){ double sum = 0; for(double d = 0; d < 10;){ d += 0.1; sum += sum + d; } }} The program compiles and runs fine. The program runs in an infinite loop because d<10 would always be true. The program has a compile error because the control variable in the for loop cannot be of the double type. The program has a compile error because the adjustment is missing in the for loop. TRUE ANSWER : ? YOUR ANSWER : ?
