What will be the output of the program?

for (int i = 0; i < 4; i += 2) 
{ 
    System.out.print(i + " "); 
} 
System.out.println(i); /* Line 5 */

[A]. 0 2 4[B]. 0 2 4 5
[C]. 0 1 2 3 4[D]. Compilation fails.

Answer: Option B

Explanation:

Compilation fails on the line 5 - System.out.println(i); as the variable i has only been declared within the for loop. It is not a recognised variable outside the code block of loop.
