Answer: Option C
Solution:
Meliodogyne sp. nematode can enter the host in wet soil through lenticels.
Meloidogyne incognita is a plant-parasitic roundworm in the family Heteroderidae. It typically incites large, usually irregular galls on roots as a result of parasitism.
Under favorable conditions (temperature, moisture, host stimulus) the J2 hatches, reaches and penetrates the host root. Root tips are the primary infection court.
