The image presents a mathematical problem related to set theory. Here's a transcription and explanation:

**Given Sets:**

- \( A = \{ x \in \mathbb{Z}^+ : x \text{ is odd} \} \)
  - This set consists of all positive odd integers.

- \( B = \{ 2, 3, 5, 6, 9, 14 \} \)
  - This set is a specific collection of integers.

- \( C = \{ x \in \mathbb{Z} : 4 \leq x \leq 12 \} \)
  - This set includes all integers \( x \) such that \( 4 \leq x \leq 12 \).

**Problem Statement:**

- Select the set corresponding to \((A \cap B) \cup C\).

**Choices:**

1. \{2, 3, 5, 6, 7, 9, 11\}
2. \{2, 3, 5, 6, 7, 9, 11, 13\}
3. \(\{ x \in \mathbb{Z} : 3 \leq x \leq 12 \}\)
4. \(\{ x \in \mathbb{Z} : 2 \leq x \leq 12 \}\)

**Explanation:**

- \( A \cap B \) is the set of elements that are both in \( A \) and \( B \). Since \( A \) contains all odd positive integers, \( A \cap B = \{3, 5, 9\} \).
- The union \((A \cap B) \cup C\) combines the elements from \( A \cap B \) with those in \( C \), avoiding duplicates.

Steps to find the result:
1. \( A \cap B = \{3, 5, 9\} \)
2. \( C = \{4, 5, 6, 7, 8, 9, 10, 11, 12\} \)
3. \((A \cap B) \cup C = \{3, 4, 5, 6, 7, 8, 9, 10, 11, 12\}
