Show answer and explanation
Correct Answer
B. {3 7} / {3 7}
ExplanationStep 1: Intersection contains common elements. Step 2: 3 and 7 are in both sets so the answer is {3 7}. Step 3: Remember intersection as the common part.
Step 1: Intersection में common elements लिए जाते हैं। Step 2: 3 और 7 दोनों sets में हैं इसलिए answer {3 7} है। Step 3: Intersection को common part की तरह याद रखें।
