In the following questions choose the word which is the exact OPPOSITE of the given words.

Q1: REVEALED

A Denied

B Concealed

C Ignored

D Overlooked

Q2: Which of the following statements are correct about the below C-program? 
#include<stdio.h>
int main()
{
    int x = 10, y = 100%90, i;
    for(i=1; i<10; i++)
    if(x != y);
        printf('x = %d y = %d\n', x, y);
    return 0;
}
1 : The printf() function is called 10 times.
2 : The program will produce the output x = 10 y = 10
3 : The ; after the if(x!=y) will NOT produce an error.
4 : The program will not produce output.

A 2, 3

B 4

C 1

D 3, 4
