B. In the water during fertilisation
C. In the water after fertilisation
D. In the ovary

Explanation

To answer the question, "Where is jelly deposited as a covering on the egg of a frog?", we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Understanding Frog Reproduction**: Frogs reproduce by laying eggs in water. The eggs need protection and a medium for fertilization.

2. **Identifying the Jelly Coating**: The jelly that covers the frog's eggs is known as the "tertiary membrane." This jelly serves several purposes, including protection and aiding in fertilization.

3. **Location of Jelly Deposition**: The jelly is deposited on the egg while it is passing through the **oviduct**. The oviduct is a tube through which the eggs travel from the ovaries to the outside of the frog's body.

4. **Function of the Jelly**: As the eggs move through the oviduct, the jelly coating is added to the eggs. This jelly helps in attracting sperm due to its jelly receptors, making fertilization easier.

5. **Conclusion**: Therefore, the correct answer to the question is that the jelly is deposited on the egg of the frog while it is in the **oviduct**.

### Final Answer:
The jelly is deposited as a covering on the egg of the frog while it is passing through the **oviduct**.
