If x, y, z ε R , the set of real numbers, then following relation does not hold
  • a)
    x > 0 and y > 0 => xy > 0
  • b)
    x, y > 0 => x + y > 0
  • c)
    x, y, z > 0 => x + y + z > 0
  • d)
    x, y > 0 => x -- y > 0
Correct answer is option 'D'. Can you explain this answer?

Option D does not hold, because
if y = 5, x = 3
x - y => 3 - 5
=> -2 < 0 (doesn't satifies the equation)
