Question

Study the following lists with reference to transmission of vital diseases:

List I	List II
(A) Zoospores of fungi	(I) Rice tungro
(B) Insects	(II) Cherry ring spot
(C) Longidorus	(III) Tobacco necrosis
(D) Seeds	(IV) Soil borne viral disease
	(V) Lettuce mosaic

Identify the sequence of Column II with respect to Column I.

• A. A- (III), B- (I), C- (II), D- (IV)
• B. A- (V), B- (I), C- (IV), D- (III)
• C. A- (III), B- (I), C- (IV), D- (V)
• D. A- (IV), B- (III), C- (II), D- (V)

Answer 1

The correct option is A A- (III), B- (I), C- (II), D- (IV)

The tobacoo necrosis virus is transmitted by zoospores of different isolates of Olpidium brassicae (a fungus).
Rice tungro disease is caused by the combination of two viruses which is then transmitted by insect, leafhoppers.

Cherry ringspot is transmitted by two species of the nematode genus, Longidorus.
The diseases present on seed are generally soil-borne or airborne.

Thus, the correct answer is option (A).
