Answer:
The Correct option is third one { 2, 3 , 5 , 7 , 8 }.
Therefore,
KUL = { 2, 3 , 5 , 7 , 8 }
Step-by-step explanation:
Set:
A set in mathematics is a collection of well defined and distinct objects, also consist of a collection of elements.
Examples given here is
K = { 2, 3 , 5 , 8 }
K is a set consist of number two, three, five, and eight.
Similarly,
L = { 3 , 5 , 7 }
L is a set consist of number three, five, and seven.
Union:
The union of a collection of sets is the set of all elements in the collection.
It is denoted as ' ∪ '
Therefore,
(K∪L) = { 2, 3 , 5 , 7 , 8 }
It is the collection of set K and L both together.
Therefore,
KUL = { 2, 3 , 5 , 7 , 8 }
