Correct answer choice is:
A. Drought.
Explanation:
The Dust Bowl is an environmental tragedy that caught the Midwest in the 1930s. A sequence of a drastic water deficiency and severe farming methods produced it. Some investigators consider it was the gravest drought in North America in 300 years.
The shortage of rain destroyed the crops that held the soil in position. When winds blew, they put immense puffs of dirt. It placed piles of dust on everything, even including residences. Dust choked cattle and created pneumonia in kids. At its gravest, the storm blew dirt to Washington, D.C.
