Solution

The correct option is B
1 - E, 2 - C, 3 - A, 4 - D

B - C = {2, 4, 6, 8, 10, 12, 14, 16} - {5, 10, 15, 20}

= {2, 4, 6, 8, 12, 14, 16}

A - C = {3, 6, 9, 12, 15, 18, 21} - {5, 10, 15, 20}

= {3, 6, 9, 12, 18, 21}

A - B = {3, 6, 9, 12, 15, 18, 21} - {2, 4, 6, 8, 10, 12, 14, 16}

= {3, 9, 15, 21}

C - (A - B) = {5, 10, 15, 20} - {3, 9, 15, 21}

= {5, 10, 20}

C $\cap$ (A - B) = {5, 10, 15, 20} ∩ {3, 9, 15, 21}

= {15}
