Question

In 1943, the causal organism and host of Bengal famine was,
A. Wheat rust by Puccinia
B. Blast of rice by Pyricularia oryzae
C. Blast of rice by Xanthomonas oryzae
D. Brown leaf spot of rice by Helminthosporium oryzae

Answer 1

Hint:- In 1943 the Bengal famine had occurred due to the consumption of rice, which create a toxic in a human body so that many or a lot of people had died without any reason because the rice plant is affected by some fungal infections which also caused many types of disease like malaria, malnutrition etc.

Complete Answer:-The Bengal famine -in 1943 there was one of the largest famines in the Bengal province of British India or eastern India(now Bangladesh ) during World War II.
An estimated 2.5 million people, out of a population of 60.3 million, died due to the very cause of starvation, malaria, and other diseases which are generally by malnutrition, population displacement, unsanitary conditions, unhygienic environment and insufficient or lack of healthcare due to food poison.
 Millions of people were suffering as the crisis marched on large segments of the economy and catastrophically disrupted social fabrication.
 More commonly, families are dismissed; men sold their small farms and business and left home to look for work or to join the British Indian Army, and women and children became shatterless and became migrants, often travelling to Calcutta or other large cities in search of organised relief.
Historians usually characterise the famine as anthropogenic or artificiality caused(man-made), A minority view survives, however, that holds that the famine was the result of some natural causes.
This is held by the British army that they introduced a new fungal disease which is caused by helminthosporium oryzae in India which directly affects the rice plant which is the main food equipment of India. It caused a brown leaf spot of rice so that rice plant can not survive which causes a large famine.

So D is the correct option.

Note:- generally two types of plants are introduced in India which caused a large problem in India firstly helminthosporium oryzae which directly affect the rice plant and another is eichornia which directly attack aquatic organisms mainly fish. So this is called Bengal famine1943, make a history.
