A. \(A\subseteq B\)
Concept
If the common part is the whole set (A), every element of (A) is also in (B). Hence \(A\subseteq B\).
Why this answer is correct
The correct answer is A. \(A\subseteq B\). If the common part is the whole set (A), every element of (A) is also in (B). Hence \(A\subseteq B\).
