The given problem is:  
**The set \((A \cap B') \cup (B \cap C)\) is equal to...**

Let’s analyze this step by step.

---

### **Expression:**  
\((A \cap B') \cup (B \cap C)\)  
- \(A \cap B'\) means **the intersection of A and the complement of B**. This contains all elements in \(A\) but not in \(B\).  
- \(B \cap C\) means **the intersection of B and C**, i.e., all elements common to both \(B\) and \(C\).

Finally, we **take the union** of these two intersections, which means combining all elements from both sets.

---

### **Options:**
- (A) \(A \cup B \cup C\)  
- (B) \(A' \cup B\)  
- (C) \(A' \cup C\)  
- (D) \(A' \cap B\)

---

### **Correct Answer:**
The correct answer is **(B) \(A' \cup B\)**.

**Reason:**  
\((A \cap B') \cup (B \cap C)\) simplifies to a set that contains all elements not in \(A\) (i.e., \(A'\)) or elements in \(B\). This is because:
1. \(A \cap B'\) contributes elements **in A but not in B**.
2. \(B \cap C\) contributes elements **common to B and C**.

Thus, the entire union is equivalent to the set \(A' \cup B\).
