Answer:
The empty set is a subset of any set.
Option 1 is correct.
Explanation:
we have to find the set which is a subset of every set.
Subset is a set of which all the elements are contained in another set. i.e
if every member of set A is contained in set B or every member of set A is also a member of set B, then A is the subset of B i.e A⊂B
{0}, {1}
The above sets which includes 0 and 1 is not necessary a member of every set. Therefore these are not correct.
The empty set is the unique set having zero elements i.e cardinality is 0
∴ we can say that all the elements of the empty set are elements of any other set. Therefore, the empty set is a subset of any set.
The empty set denoted by Ф or {} is a subset of any set.
Option 1 is correct.
