Options

A. Cercaria
B. Planula
C. cysticercus
D. Muller's larve

Answer

**Step-by-Step Text Solution:**

1. **Identify the Larva**: The larva of schistosome is known as cercaria.

2. **Life Cycle Overview**: Schistosomes are a type of flatworm that undergo a complex life cycle. The cercaria is a free-swimming larval stage that emerges from the intermediate host, usually a freshwater snail.

3. **Infection Process**: When cercaria come into contact with a suitable host, such as humans, they can penetrate the skin and enter the bloodstream.

4. **Migration**: After entering the human body, the cercaria migrate to the liver, where they mature into adult worms.

5. **Maturation**: The adult schistosomes reside in the blood vessels, particularly around the intestines or bladder, depending on the species.

6. **Reproduction**: Once mature, the adult worms reproduce and lay eggs. These eggs can then be expelled from the body through urine or feces, continuing the cycle.

7. **Health Implications**: Schistosome infections can lead to various health issues, including schistosomiasis, which can cause significant morbidity.
