Answer with Step-by-step explanation:
Suppose a set B.
We have to describe why for any set B, empty set would be a subset of it.
Empty set : It is that set which contain no element.
It is represented as or {}.
When an empty set contain no element then empty set would be be a subset of any set .
If a set B={1,2}
Then , empty set will be a subset of B.
Hence, empty set would be a subset of any set B.
