Which option correctly matches control in animals and plants?
Answer and explanation
Correct answer: Nerves and hormones in animals and mainly chemical control in plants
The governing concept is coordination in living organisms. Animals use the nervous system for rapid responses and hormones for slower, longer-lasting regulation. Plants have no brain or nervous system; they coordinate activities mainly through chemical messengers such as plant hormones and through growth responses. Therefore option A correctly compares both groups. The other choices assign structures that do not perform control in the stated organisms.
