A) Rice B) Jute
C) Jute D) Pongamia
E) Petunia F) Lichens

Options

A. All the above
B. A,B,C,D only
C. A,C only
D. F only

Answer

To determine which of the given plants provide economically useful products under provisioning services, we will analyze each plant one by one.

### Step-by-Step Solution:

1. **Identify the Plants**: The plants listed in the question are:
- A) Rice
- B) Jute
- C) Jute (repeated)
- D) Pongamia
- E) Petunia
- F) Lichens

2. **Define Provisioning Services**: Provisioning services refer to the products obtained from ecosystems that are directly used by humans, such as food, raw materials, and medicinal resources.

3. **Analyze Each Plant**:
- **Rice (A)**: Rice is a staple food crop that is directly consumed by humans. Therefore, it is classified under provisioning services.
- **Jute (B)**: Jute is a fiber plant used to make bags, clothes, and other materials. It is also classified under provisioning services.
- **Jute (C)**: This is a repetition of the previous entry and holds the same classification as above.
- **Pongamia (D)**: Pongamia is known for its oil, which has medicinal properties and can be used for biodiesel. Thus, it is also classified under provisioning services.
- **Petunia (E)**: Petunia is primarily an ornamental flower and does not provide direct economic products that are considered provisioning services.
- **Lichens (F)**: Lichens are composite organisms that serve as pollution indicators and do not provide economically useful products. Therefore, they are not classified under provisioning services.

4. **Conclusion**: The plants that provide economically useful products under provisioning services are:
- Rice (A)
- Jute (B)
- Jute (C) (repeated)
- Pongamia (D)

Thus, the answer is **A, B, C, D**.
