Suppose that x is an int variable. Which of the following expressions always evaluates to false?

A) (x > 0) || (x<=0)
B) (x > 0) || (x == 0)
C) (x > 0) && ( x<=0)
D) (x >= 0) && (x == 0)

Option C evaluates to false because (x > 0) is true when x is a positive number and (x <= 0) is true when x is a non-positive number (zero or negative). Therefore, (x > 0) && (x<=0) is always false since the statements are contradictory.
