The intermediate host in the life-cycle of liver fluke is

Options

A. Pila
B. Snail
C. Sheep
D. pig

Answer

To determine the intermediate host in the life cycle of the liver fluke (Fasciola hepatica), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organism**: The organism in question is the liver fluke, scientifically known as Fasciola hepatica.

2. **Understand the Life Cycle**: The liver fluke has a complex life cycle that includes both primary and intermediate hosts.

3. **Define Primary Host**: In the case of Fasciola hepatica, the primary host is typically a sheep. This is where the adult liver flukes reside and reproduce.

4. **Identify the Intermediate Host**: The intermediate host is crucial for the development of the liver fluke's larvae. In the case of Fasciola hepatica, the larvae develop in a specific type of organism.

5. **Select the Correct Option**: Among the options provided (Pila, snails, sheep, and pig), the correct intermediate host for the liver fluke is snails. Snails are where the larvae of the liver fluke develop before they can infect the primary host.

### Final Answer:
The intermediate host in the life cycle of the liver fluke is **snails**.
