If A= {2, 4, 6}, B= {1, 2, 5, 7}, and C= {2, 3, 4, 6}. Find A-(B U C)  Choose the correct choice from the following.
A) {1 , 2}
B) {2 ,3 ,5 }
C) { }
D) {5 }
E) None of these
Explanation :   A= {2, 4, 6},   B= {1, 2, 5, 7},   C = {2, 3, 4, 6}   Now,(B U C) = {1, 2, 5, 7} U {2, 3, 4, 6} = {1,2,3,4,5,6,7}   A-(B U C) = {2, 4, 6} - {1,2,3,4,5,6,7} = { }   Hence (C) is correct answer.   Answer : { }
