The Correct Option is A
Approach Solution - 1
Anguina tritici, also known as the wheat seed gall nematode, infects wheat ears, leading to the formation of galls that replace normal grains. This results in the 'yellow ear rot' disease, characterized by discolored and deformed ears, leading to significant yield losses.

Symptom-to-Species Match: 'Yellow ear rot' names both the crop part affected (ear) and the nematode responsible — memorize this pairing directly.
Anguina tritici, the wheat seed gall nematode, infects wheat ears and replaces normal grains with galls, producing the discolored, deformed 'yellow ear rot' symptom.
Heterodera avenae (cereal cyst), Pratylenchus thornei (root lesion), and Ditylenchus dipsaci (stem nematode) all attack different plant parts and cause different named diseases.
