Question 1/1 Easy Mathematics Relations and Functions Binary operations Class 12 Level 28

Explanation opens after your attempt
Correct Answer

A. बंदताClosure

Step 1

Concept

बंदता का मतलब है कि संक्रिया करने के बाद परिणाम समुच्चय से बाहर न जाए। / Closure means the result does not leave the set after the operation.

Step 2

Why this answer is correct

यहाँ (a*b) फिर से (A) में है, इसलिए बंदता है। / Here (a*b) again lies in (A), so closure holds.

Step 3

Exam Tip

द्विआधारी संक्रिया पहचानने का पहला संकेत बंदता है। / Closure is the first sign to check in binary operation questions.
