Answer:
{ 9 , 10 }
Option A is the correct option.
Step-by-step explanation:
Let the sets be A and B
A = { 7 , 8 , 9 , 10 }
B = { 9 , 10 , 11 , 12 }
The intersection of sets A and B is the set of all ements which belongs to both A and B.
The intersection of sets A and N is denoted by ( A ∩ B ) and read as A intersection B.
A ∩ B = { 7 , 8 , 9 , 10 } { 9 , 10 , 11 , 11 , 12 }
Now, list the elements which are present in both sets. A ∩ B = { 9 , 10 }
Hope I helped!
