Consider the given statements about a type of fertilisation.
- Both male and female release gametes outside the body
- Zygote develops outside the parent's body
Identify the type of fertilisation and select the option that correctly identifies the animal in which this type of fertilisation occurs.

Options

A.
B.
C.
D.

Explanation

To solve the question, we need to analyze the statements provided regarding fertilization and identify the type of fertilization and the animal associated with it.

### Step-by-Step Solution:

1. **Understanding the Statements**:
- The first statement mentions that both male and female release gametes outside the body.
- The second statement indicates that the zygote develops outside the parent's body.

2. **Identifying the Type of Fertilization**:
- The process where gametes (sperm and egg) are released outside the body and fertilization occurs in an external environment is known as **external fertilization**.

3. **Examples of Animals with External Fertilization**:
- External fertilization is commonly observed in aquatic animals, such as fish and amphibians. In these species, the eggs and sperm are released into the water, where fertilization occurs.

4. **Selecting the Correct Animal**:
- Given that external fertilization is typical in animals like fish, frogs, and certain invertebrates, we can conclude that an animal such as a fish would be an appropriate example of an organism that undergoes external fertilization.

5. **Final Answer**:
- Therefore, the type of fertilization described is **external fertilization**, and a suitable example of an animal that exhibits this type of fertilization is **fish**.
