ANSWERS WITH SOLUTION:

2. B - D

   Solution:

   {5, 7, 9} - {2, 4, 6, 8} = {2, 4, 5, 6, 7, 8, 9} <---- Answer

3. (A U B) - C

   Solution:

   A U B = {2, 5} U {5, 7, 9} = {2, 5, 7, 9}

   A U B - C = {2, 5, 7, 9} - {1, 3, 5, 7} = {1, 2, 3, 9} <---- Answer

4. D - (B ∩ A)

   Solution:

   B ∩ A = {5, 7, 9} ∩ {2, 5} = {5}

   B ∩ A - C = {5} - {1, 3, 5, 7} = {1, 3, 7} <---- Answer
