    C Virus Correct Answer Incorrect Answer
    D Bacteria Correct Answer Incorrect Answer
    E Nematode Correct Answer Incorrect Answer

    Solution

    The Little leaf disease of brinjal is caused by a phytoplasma, which is a type of bacteria-like organism that lacks a cell wall. Phytoplasmas are transmitted primarily by insect vectors, especially leafhoppers, and they interfere with the normal growth of the plant, causing the leaves to become smaller, twisted, and deformed. Although it resembles a bacterial infection, phytoplasma is distinct due to its unique characteristics.
