To solve the question regarding the sexually transmitted disease characterized by the development of chancres on the genitals, we need to analyze the options provided.

### Step-by-Step Solution:

1. **Understand the Symptoms**: The question states that the sexually transmitted disease is symptomized by the development of chancres on the genitals. Chancres are sores that typically appear in the primary stage of syphilis.

2. **Identify the Options**: The options given are:
- A) Treponema pallidum
- B) Neisseria gonorrhoeae
- C) Human Immunodeficiency Virus (HIV)
- D) Hepatitis B Virus

3. **Analyze Each Option**:
- **Treponema pallidum**: This is the bacterium that causes syphilis, which is known for causing chancres.
- **Neisseria gonorrhoeae**: This bacterium causes gonorrhea, which does not typically present with chancres but rather with symptoms like burning sensation during urination and discharge.
- **Human Immunodeficiency Virus (HIV)**: This virus leads to AIDS and does not cause chancres.
- **Hepatitis B Virus**: This virus affects the liver and does not cause chancres.

4. **Determine the Correct Answer**: Since the development of chancres is specifically associated with syphilis, and Treponema pallidum is the causative agent of syphilis, the correct answer is A) Treponema pallidum.

### Final Answer:
The sexually transmitted disease symptomized by the development of chancres on the genitals is caused by the infection of **Treponema pallidum**.
