Answer:
The first set (Set B) is the null set.
Step-by-step explanation:
I will list the contents of each of the sets.
Set 1:
B = {the whole numbers between 10 and 11}
B = {}
Set 2:
The set of all prime numbers divisible by 2.
{2}
Set 3:
The set of odd natural numbers divisible by 3.
{3, 9, 15, 21, 27, ...}
Set 4:
The set of even natural numbers divisible by 3.
{6, 12, 18, 24, 30, ...}
As we can see from the list, only Set 1 contains nothing. That is the empty or null set.
Hope this helps!
