The correct answer is A) Insufficient rainfall.
Drought is a period of time when a region or area receives less than its average annual precipitation. This can lead to a number of problems, including crop failures, water shortages, and wildfires.
Karnataka is a state in southern India that is prone to drought. The state receives most of its rainfall during the monsoon season, which runs from June to September. However, in recent years, the monsoon has been erratic, leading to drought conditions in some parts of the state.
In 2018, for example, Karnataka experienced its worst drought in over 40 years. The state received only 60% of its average annual rainfall, and many farmers were forced to leave their land.
The government of Karnataka has taken a number of steps to address the problem of drought, including providing financial assistance to farmers and building water storage tanks. However, the state is still vulnerable to drought, and it is important to take steps to mitigate the effects of this natural hazard.
