Options:

8
✅Explanation:
• The nematode life cycle typically consists of six distinct stages:
Egg: The first stage is the egg, which contains the developing embryo.
First-stage juvenile (J1): This stage often develops within the egg and emerges upon hatching.
Second-stage juvenile (J2): This is usually the infective stage that seeks out and invades a host.
Third-stage juvenile (J3): Further development occurs inside the host.
Fourth-stage juvenile (J4): The final juvenile stage before adulthood.
Adult: The mature nematode, capable of reproduction.
