B. 50,51,52,
C. 51,52,53,
D. Compiler error
Solution: The semicolon after the WHILE (Condition) is missing.

  i++;
}while(true);
A. A,B,C,
B. A,B,C
C. Runtime Exception with Index Of Bounds Exception
D. Compiler error
Solution: no solution

}
A. 1,2,3,4
B. 1,2,3,4,
C. 1,2,3,4,5,
D. 1,2,3,4,5

}
A.  1,2,3,
B. 1,2,3
C. 1,2,3,4,
D. 1,2,3,4
Solution: BREAK condition is checked after printing the variable "score". So, it prints 4 also.
