Solution
We have the following sets:
A = {2, 3, 4} and B = {5, 2, 6, 3, 8, 4, 9}
And we need to verify if:
A is subset of B
Correct, each element from A belongs to B
B is subset of A
False, each element of B not belongs to A
A is complementary set of B
False, all the elements from A are in B
All the choices are correct
False
Then the final answer is:
A is subset of B
