The growing size of the human population is a cause of concern for all people. The rate of birth and death in a given population will determine its size. Reproduction is the process by which organisms increase their population. The process of sexual maturation for reproduction is gradual and takes place while general body growth is still going on. Some degree of sexual maturation does not necessarily mean that the mind or body is ready for sexual acts or for having and bringing up children. Various contraceptive devices are being used by human beings to control the size of population.
Which contraceptive method changes the hormonal balance of the body?

Options

A. Condoms
B. Diaphragms
C. Oral pills
D. Both (a) and (b)

Explanation

To answer the question regarding which contraceptive method changes the hormonal balance of the body, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Contraceptive Methods**: Contraceptive methods are designed to prevent pregnancy. They can be broadly categorized into physical barriers and hormonal methods.

2. **Identifying Physical Barrier Methods**:
- **Condoms**: These are used by both males and females to block direct contact between genital organs. They do not alter hormonal balance.
- **Diaphragm**: This is a rubber barrier used by females. Like condoms, it prevents sperm from entering the uterus but does not change hormonal levels.

3. **Identifying Hormonal Methods**:
- **Oral Pills**: These are taken by females and are designed to disrupt the hormonal balance in the body. They can prevent ovulation and alter the menstrual cycle.

4. **Evaluating the Options**:
- Since condoms and diaphragms are physical barriers, they do not affect hormonal balance. The oral pill, however, is specifically designed to change hormonal levels in the body.

5. **Conclusion**: The contraceptive method that changes the hormonal balance of the body is the **Oral Pill**.

### Final Answer:
The contraceptive method that changes the hormonal balance of the body is the **Oral Pill**.
