Which of the following is a sedentary semi-endoparasite?

✅Explanation:
Sedentary semi-endoparasite: This refers to a type of plant-parasitic nematode where the adult female becomes partially embedded within the root tissue, with the posterior part of its body remaining outside. It establishes a permanent feeding site and does not move once established.
Rotylenchulus reniformis: This nematode, also known as the reniform nematode, fits the description of a sedentary semi-endoparasite. The female enters the root and establishes a feeding site, causing damage to the plant.

🔑Key Points:
Meloidogyne hapla:This is a root-knot nematode, which is a sedentary endoparasite (completely embedded in the root).
Anguina tritici:This is a seed gall nematode that infects seeds.
Aphelenchoides besseyi:This is a foliar nematode, which infects above-ground plant parts like leaves and stems.
