Correct Answer

A. ({1,3,5,6,7,9,11,12})

Step 1

Concept

(A-B={2,4,8,10}). Its complement in (U) is ({1,3,5,6,7,9,11,12}).

Step 2

Why this answer is correct

The correct answer is A. ({1,3,5,6,7,9,11,12}). (A-B={2,4,8,10}). Its complement in (U) is ({1,3,5,6,7,9,11,12}).

Step 3

Exam Tip

(A-B={2,4,8,10}) है। इसका (U) में पूरक ({1,3,5,6,7,9,11,12}) है।
