Question

If A = { $x:x$ is an even natural number} and B = { $y:y$ is a natural number}, then _______________.

• A. A is a subset of B
• B. B is a subset of A
• C. A is the superset of B
• D. B is the superset of A

Answer 1

Answer: (A), (D)

The correct options are
A A is a subset of B
D B is the superset of A

Given that,
set A = {2, 4, 6, 8, 10, 12, …} and set B = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 …}.
It is clear that all the elements of set A are included in set B.
Hence, set A is the subset of set B or A ⊂ B, and, B is the superset of A.
