Question

Bio-diesel is extracted from the following plant:

• A. Hibiscus
• B. Aloe Vera
• C. Jatropha
• D. Chamomile

Hint:

Think about the hardy shrub India promoted for wasteland plantations to produce fuel oil.

Answer 1

The Correct Option is C

Step 1: Recall what biodiesel needs.
Biodiesel is made from plant oils that are chemically treated to work as a diesel substitute, so the source plant needs oil rich seeds.

Step 2: Identify the plant known for this in India.
Jatropha curcas is a hardy shrub that grows on wasteland and produces seeds with a high oil content, which is why the Indian government promoted it for biodiesel programs.

Step 3: Check the remaining plants.
Hibiscus, Aloe Vera, and Chamomile are grown for flowers, gel, or herbal use, none of which involve extracting seed oil for fuel.

Final Answer:
Biodiesel is extracted from Jatropha. \[ \boxed{\text{Jatropha}} \]
