D. None of the above

Answer 1

Hint: Here, we will start looking at all the possible diseases that are related to the potato and then find the disease that was specific for the Irish famine.

Complete answer: Here, the question is asking about one of the greatest famine that led to the destruction of entire potato crops in Ireland during the year 1845 to 1849.
Since all the disease belongs to the potato so we need to specifically go back to history to find out the main disease.
The crop failure in 1845-1849 is attributed to the Late blight of potatoes.
It leads to the destruction of both the leaves and edible tubers or roots of the potato plant.

Additional information: The disease mentioned in the options are caused by-
A. Late blight of potato - Phytophthora infestans
B. Early blight of potato - Alternaria solani
C. Dry rot of potato - Fusarium sp.
More than 1 million people died in the Irish famine and about one half of the potato crop destroyed the infestation period followed by the loss of almost three-quarters of the crop in the consecutive next seven years.

Therefore, the correct option is A. Light blight of potato.

Note: The Irish famine is related to the disease of potato that is Late blight of potato caused by Phytophthora infestans.
