Detailed Solution

The role of the effector in a reflex arc is to carry out the motor response generated by the integrating centre.

A reflex arc is a neural pathway that mediates a reflex action. It involves several components, including a receptor, a sensory neuron, an integrating centre, a motor neuron, and an effector. When a receptor detects a stimulus, it generates a sensory signal that is transmitted by the sensory neuron to the integrating centre in the CNS, where the information is processed and a motor response is generated. The motor response is then carried out by the effector.

The effector is a muscle or gland that carries out the motor response generated by the integrating centre.
