Answer

To solve the question regarding the mammary gland of a woman, we will analyze the options provided and understand the characteristics of the mammary gland.

### Step-by-Step Solution:

1. **Understanding the Function of Mammary Glands**:
- Mammary glands are primarily responsible for producing milk in females. This function is crucial for nourishing infants.

**Hint**: Remember that mammary glands are associated with lactation.

2. **Identifying the Structure of Mammary Glands**:
- Structurally, mammary glands are classified as modified sweat glands. They originate from the modification of sweat glands during embryonic development.

**Hint**: Think about how sweat glands and mammary glands are related in terms of their origin.

3. **Presence in Both Sexes**:
- While mammary glands are present in both males and females, they are functional (i.e., produce milk) only in females. This is an important distinction to make.

**Hint**: Consider the functional differences between male and female mammary glands.

4. **Analyzing the Options**:
- **Option 1**: A modified sweat gland - This is correct based on our understanding of their structure.
- **Option 2**: A primary sex organ - This is incorrect as mammary glands are not classified as primary sex organs.
- **Option 3**: An exocrine gland - This is also correct because mammary glands secrete milk through ducts.
- **Option 4**: Both A and C - This option is correct since mammary glands are both modified sweat glands and exocrine glands.

5. **Selecting the Best Option**:
- Since option 4 encompasses both correct aspects (A and C), it is the most comprehensive answer. Therefore, the correct answer is **Option 4: Both A and C**.

### Final Answer:
The mammary gland of a woman is **both a modified sweat gland and an exocrine gland**.
