Options

A. Ant, Pituitary
B. Post Pituitary
C. Graafian follical
D. Corpus luteum

Answer

To answer the question about the hormone that supports pregnancy and stimulates mammary glands for the formation of alveoli for storing milk, we can follow these steps:

### Step 1: Identify the Role of Hormones in Pregnancy
- Hormones play crucial roles in various physiological processes, including pregnancy and lactation. During pregnancy, certain hormones are essential for maintaining the pregnancy and preparing the body for childbirth and breastfeeding.

**Hint:** Think about the hormones involved in pregnancy and lactation.

### Step 2: Focus on the Hormones Related to Mammary Gland Development
- During pregnancy, the mammary glands undergo changes to prepare for milk production. This involves the development of alveoli, which are the structures in the mammary glands that store milk.

**Hint:** Consider which hormones are known to influence the development of mammary glands.

### Step 3: Identify the Specific Hormone
- The hormone that is primarily responsible for supporting pregnancy and stimulating the mammary glands for the formation of alveoli is **prolactin**. Prolactin is secreted by the anterior pituitary gland and is crucial for milk production and mammary gland development.

**Hint:** Recall the gland that secretes prolactin and its role in lactation.

### Step 4: Confirm the Source of the Hormone
- Prolactin is secreted from the **anterior pituitary gland**. This gland is located at the base of the brain and is responsible for producing several important hormones, including prolactin.

**Hint:** Remember the location of the anterior pituitary gland and its function.

### Final Answer
The hormone that supports pregnancy and stimulates mammary glands for the formation of alveoli for storing milk is **prolactin**, which is secreted from the **anterior pituitary gland**.
