Options

A. Thyroid
B. Mammary
C. Pituitary
D. Thymus

Answer

**Step-by-Step Solution:**

1. **Identify the Gland:** The question asks which gland in females undergoes differentiation during pregnancy. The gland in question is the mammary gland.

2. **Understanding Differentiation:** During pregnancy, the mammary gland undergoes extensive changes. This process is known as differentiation, where the gland develops the necessary structures to prepare for milk production.

3. **Development of Alveolar Lobules:** As the mammary gland differentiates, it develops functional structures called alveolar lobules. These lobules are essential for milk production.

4. **Role of Alveolar Lobules:** The alveolar lobules are responsible for producing milk, which is crucial for feeding the newborn after birth.

5. **Initial Milk Production:** The first milk produced after childbirth is known as colostrum. Colostrum is rich in antibodies, particularly IgA, which helps provide immunity to the newborn.

6. **Conclusion:** Therefore, the gland that undergoes differentiation during pregnancy is the mammary gland, which prepares for lactation by developing alveolar lobules.

**Final Answer:** The mammary gland undergoes differentiation during pregnancy.
