A. \(B\subseteq A\)
Concept
\(A\cup B=A\) means all elements of (B) are already in (A). Hence \(B\subseteq A\).
Why this answer is correct
The correct answer is A. \(B\subseteq A\). \(A\cup B=A\) means all elements of (B) are already in (A). Hence \(B\subseteq A\).
Exam Tip
\(A\cup B=A\) का अर्थ है कि (B) के सभी अवयव (A) में पहले से हैं। अतः \(B\subseteq A\) है।
