If \(A\setminus B\subseteq A\cap C\), which conclusion must be true?
Answer and explanation
Correct answer: \(A\setminus B\subseteq C\)
The hypothesis says every element of \(A\setminus B\) belongs to the intersection \(A\cap C\). An element of an intersection belongs to both component sets, so every such element must belong to \(C\). Hence, by transitivity of inclusion, \(A\setminus B\subseteq C\). No relation between all of \(A\), \(B\), and \(C\) is forced.
