Answer:
Correct Answer: A
Solution:
The disease appears in the form of shiny white, smooth, raised irregular blisters or patches on the leaves or stems.
The pressure from below of the upwardly growing sporangiophores and the sporangia causes the host epidermis to bulge and finally to burst over the sporangial sorus.
The sporangial masses are exposed as a crust of white, blister-like patches.
Therefore, white rust is also called blister rusts.
