As we learnt 

 

UNION OF SETS -

 

Let A and B be any two sets. The union of A and B is the set which consists of all the elements of A and all the elements of B, the common elements being taken only once. The symbol ‘∪’ is used to denote the union.

- wherein

Symbolically, we write A U B = {x: x ∈ A or x ∈ B}.

 

 Here union of these three sets is all the elements in these three sets.

 


Option 1)

{1,2,3,4,5,8,7,9}

Option 2)

{1,2,3,5,7,8,9}

Option 3)

{1,2,3,4,7,8,9}
