A parasite will be called successful parasite which ?

Options

A. Grows rapidly
B. Reproduces fast
C. Makes minimum demands from its host
D. Sticks to host for long

Explanation

To determine when a parasite can be considered a successful parasite, we can follow these steps:

### Step-by-Step Solution:

1. **Definition of a Parasite**:
A parasite is an organism that lives on or inside a host organism and derives nutrients at the host's expense.

2. **Characteristics of a Successful Parasite**:
A successful parasite is one that can live within its host without causing significant harm or distress to the host. This allows the parasite to thrive and reproduce.

3. **Minimum Demands from Host**:
A successful parasite makes minimal demands from its host. This is crucial because if the parasite extracts too many resources or causes significant harm, it can lead to the host's death.

4. **Impact of Excessive Demands**:
If a parasite makes excessive demands on the host, it can cause abnormalities and symptoms in the host. This can trigger the host's immune response, which may lead to the death of the parasite.

5. **Longevity and Reproduction**:
By making minimal demands, the parasite can remain in the host for a longer duration, which increases its chances of reproduction and survival.

6. **Conclusion**:
Therefore, a parasite will be called a successful parasite if it makes minimum demands from its host.

### Final Answer:
A parasite will be called a successful parasite if it makes minimum demands from its host.
