Question

1. If A is a subset of U, which one of the following relation is always true? (A) A U U = U (B) An U = U (C) An A = 0 (D) AU O = 0​

Answer 1

Answer:

Now, in the second venn diagram we can see A

C

as a region marked with lines and in the third venn diagram we can see B

C

as a region marked with lines.

Clearly it can be seen that B

C

is the subset of A

C

.

Hence, option B is correct.
