If x = (all prime factors of 44) and y = (all prime factors of…

If x = (all prime factors of 44) and y = (all prime factors of 60), the elements of X ∪ Y and X ∩ Y respectively are
  • A.
    (2, 4, 3, 5, 11) and (4)
  • B.
    (4, 3, 5, 11) and (3, 4)
  • C.
    (2, 5, 11) and (2)
  • D.
    (2, 3, 5, 11) and (2)
Correct Answer: Option D
Explanation

x = (all prime factors of 44) and y = (all prime factors of 60)
∴ x = (2, 11), y = (2, 3, 5)
X ∪ Y = (2, 3, 5, 11),
X ∩ Y = (2)
