Options

A. organic chemistry
B. physical chemistry
C. inorganic chemistry
D. nuclear chemistry

Answer

To answer the question regarding the branch of chemistry that deals with the study of hydrocarbons and their derivatives, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Hydrocarbons**:
- Hydrocarbons are organic compounds that consist entirely of hydrogen and carbon. They are the fundamental building blocks of organic chemistry.

2. **Identifying the Relevant Branch of Chemistry**:
- Chemistry is divided into various branches, including:
- **Nuclear Chemistry**: Focuses on the reactions and properties of atomic nuclei.
- **Inorganic Chemistry**: Deals with inorganic compounds, which do not primarily contain carbon-hydrogen bonds.
- **Physical Chemistry**: Studies the physical properties and changes of chemical systems, including thermodynamics and kinetics.
- **Organic Chemistry**: This branch specifically focuses on the study of carbon-containing compounds, including hydrocarbons and their derivatives.

3. **Conclusion**:
- Since hydrocarbons are organic compounds and their study falls under the category of carbon-based chemistry, the correct answer is **Organic Chemistry**.

### Final Answer:
The branch of chemistry which deals with the study of hydrocarbons and their derivatives is termed as **Organic Chemistry**.
