Source of liquid hydrocarbons is

Options

A. Euphobiacae
B. Asclepiadaceae
C. Apocyananaceae
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Hydrocarbons**: Hydrocarbons are organic compounds made up of hydrogen and carbon atoms. They can be found in different forms, including gases, liquids, and solids.

2. **Identifying the Source**: Liquid hydrocarbons can be derived from various natural sources, particularly from plants that produce latex. Latex is a milky fluid found in many plants, which can contain hydrocarbons.

3. **Photosynthesis and Hydrocarbon Production**: Plants undergo photosynthesis, a process where they convert sunlight into energy, producing glucose and other byproducts. Some of these byproducts can be converted into latex, which is a source of liquid hydrocarbons.

4. **Examples of Plants**: Several plant species are known to produce latex that contains liquid hydrocarbons. Notable examples include:
- **Euphorbia**: A genus of flowering plants known for their milky latex.
- **Acalypha**: Another genus that produces latex.
- **Apocynaceae**: A family of flowering plants that also produces latex.

5. **Conclusion**: Therefore, the source of liquid hydrocarbons can be attributed to various flowering plants that produce latex, including Euphorbia, Acalypha, and Apocynaceae.

6. **Final Answer**: The correct answer to the question is "all of the above," as all mentioned plant families are sources of liquid hydrocarbons.
