To solve the problem, we need to identify the plant whose latex is the source of biodiesel.

1. Latex and Biodiesel:
Biodiesel is a renewable source of energy that can be produced from various plants. The latex of certain plants is used for extracting oils that are converted into biodiesel.

2. Identifying the Plant:
- Sapota (Option A) is known for its sweet fruit, but it is not a source of biodiesel.
- Chicle (Option B) is the latex derived from the sapodilla tree and is not related to biodiesel production.
- Hevea (Option C) is the rubber tree, whose latex is used for making rubber, not biodiesel.
- Jatropha (Option D) is a plant whose seeds contain oil that can be converted into biodiesel. The latex from Jatropha is used for biodiesel production.

Final Answer:
The latex of the Jatropha plant is the source of biodiesel (Option D).
