Which option demonstrates the effect of pesticides on insects according to the material?

• A. Digestive system
• B. Nervous system
• C. Circulatory system
• D. Skeletal system; Respiratory system; Growth Regulation

Answer: (D)

Pesticides can affect insects through several body systems, not just one. The material describes how some products disrupt the insect’s structural integrity and development as well as respiration: effects on the exoskeleton (skeletal system), on the breathing apparatus (respiratory system), and as growth regulators that interfere with proper development. This broad range shows that pesticides can act beyond neural or digestive targets, including how they hinder molting and weaken the exoskeleton. Because the material covers these multiple targets and developmental disruptions, the option listing skeletal system, respiratory system, and growth regulation best aligns with what is described. The other options focus on a single system, which doesn’t capture the range of pesticide actions presented.
