C. pancreatic gland
D. thyroid gland.

Explanation

**Step-by-Step Solution:**

1. **Identify Stenson's Duct**: Stenson's duct is a specific duct associated with a gland in the human body. It is important to know which gland it is linked to in order to answer the question correctly.

2. **Consider the Options**: The options given are:
