Why was DDT widely used after World War II?
Correct Answer: B. It helped control malaria and insect-borne diseases.
Explanation: DDT was extensively utilized following World War II primarily because of its effectiveness in eradicating insects that transmit deadly diseases like malaria and typhus. During this era, it served as a critical tool for public health initiatives and was also widely adopted in agriculture to protect crops from pests. Unlike some modern claims, it was not a fertilizer and was later banned in many regions because it is not biodegradable and can cause significant environmental harm. Therefore, its primary historical value was its role in controlling insect-borne illnesses and safeguarding food supplies.
