D. pituitary gland.

Explanation

**Step-by-Step Solution:**

1. **Identify the Hormones**: TSH stands for Thyroid Stimulating Hormone, and ACTH stands for Adenocorticotropic Hormone. Both are important hormones in the human body.

2. **Understand the Source of Secretion**: TSH and ACTH are secreted by the pituitary gland, which is often referred to as the "master gland" of the endocrine system.

3. **Function of TSH**: TSH stimulates the thyroid gland, which is located in the neck, to produce thyroid hormones (T3 and T4). These hormones are crucial for regulating metabolism, growth, and development.

4. **Function of ACTH**: ACTH stimulates the adrenal glands to produce cortisol and other hormones that are important for stress response and metabolism.

5. **Conclusion**: Therefore, both TSH and ACTH are secreted by the pituitary gland.

**Final Answer**: TSH and ACTH are secreted by the pituitary gland.
