Question

Identify correct matching of the following diseases:

(Note: The question header in the source image mentioned "viral diseases observed in plants" which appears to be a context error as Scrapie is an animal prion disease, but the matching task is clear.)

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

Hint:

{Scrapie} is a key example of a {Prion} disease (proteinaceous infectious particle), distinct from viral diseases.

Answer 1

The Correct Option is C

Step 1: Match the Pairs:

• A. Scrapie: A fatal degenerative disease affecting the nervous system of Sheep and goats. It is caused by Prions.
  Match: A - IV.
• B. Vein clearing: A common symptom of viral infection in plants, notably Bhendi (Yellow Vein Mosaic of Okra).
  Match: B - III.
• C. Malformation: Cocoa Swollen Shoot Virus causes swelling and malformation. (Also Mango malformation exists, but Cocoa is the remaining option suitable for 'malformation' or swelling symptoms in this set).
  Match: C - II.
• D. Breaking of flowers: Refers to the "breaking" (streaking) of flower color, famously caused by the Tulip Breaking Virus in Tulip.
  Match: D - I.

Step 2: Conclusion:
The correct matching sequence is A-IV, B-III, C-II, D-I. This corresponds to Option (C).
