C. Pineal gland
D. Parathyroid gland

Answer

To solve the question "Which of the following glands consists of two lobes, interconnected with a thin flap of connective tissue?", we can follow these steps:

### Step 1: Identify the Glands
We need to consider the options provided:
- Pituitary gland
- Thyroid gland
- Pineal gland
- Parathyroid gland

### Step 2: Analyze Each Gland
1. **Pituitary Gland**: This gland is often referred to as the "master gland" and is not bilobed; it has an anterior and posterior part but is not structured as two lobes connected by connective tissue.

2. **Thyroid Gland**: This gland is known to have two lobes (right and left) that are connected by a thin flap of connective tissue called the isthmus. It is butterfly-shaped and located on either side of the trachea.

3. **Pineal Gland**: This gland is a small, pea-shaped gland located in the brain and does not have a bilobed structure.

4. **Parathyroid Gland**: These glands are typically four small glands located on the back of the thyroid gland and do not have a bilobed structure.

### Step 3: Conclusion
After analyzing the structure of each gland, we can conclude that the **Thyroid Gland** is the only gland that consists of two lobes interconnected with a thin flap of connective tissue.

### Final Answer
The correct answer is the **Thyroid Gland**.
