यदि \(A=\{a,b,c,d\}\) और \(B=\{b,d,e\}\) है, तो (A-B) क्या होगा?

If \(A=\{a,b,c,d\}\) and \(B=\{b,d,e\}\), what is (A-B)?

Explanation opens after your attempt
Correct Answer

A. ( {a,c} )

Step 1

Concept

(A-B) contains elements of (A) that are not in (B). While finding difference, remove the common elements from (A).

Step 2
