Question: 1 -

Which statement is true?

public void test(int x)
{
	int odd = 1;
	if(odd) /* Line 4 */
	{
		System.out.println("odd");
	}
	else
	{
		System.out.println("even");
	}
}

"odd" will always be output.

"even" will always be output.

"odd" will be output for odd values of x, and "even" for even values.
