K = {2, 3, 5, 8}
L = {3, 5, 7}
a. { }
b. {3, 5}
c. {2, 3, 5, 7, 8}
d. {2, 7, 8}

Answer 1

AuBuCuDuKuL={2,3,5,7,8}

Answer 2

Union of the represented sets should include all the sets without repetition
Here is an example for substituton
`A= {1,2,3} B={3,4,5} A union B = {1,2,3,4,5}`. So, logically, the answer is c. {2, 3, 5, 7, 8}
