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)
