किस स्थिति में \(\mathcal{P}(A)\subseteq \mathcal{P}(B)\) सत्य होगा?
In which condition is \(\mathcal{P}(A)\subseteq \mathcal{P}(B)\) true?
Explanation opens after your attempt
Correct Answer
A. जब \(A\subseteq B\)When \(A\subseteq B\)
Concept
If \(A\subseteq B\), every subset of (A) is also a subset of (B). So the same inclusion holds for power sets.
Why this answer is correct
The correct answer is A. जब \(A\subseteq B\) / When \(A\subseteq B\). If \(A\subseteq B\), every subset of (A) is also a subset of (B). So the same inclusion holds for power sets.
Exam Tip
यदि \(A\subseteq B\), तो (A) का हर उपसमुच्चय (B) का भी उपसमुच्चय होगा। इसलिए घात समुच्चयों में भी यही समावेशन रहता है।
