Final answer:
Driving on autopilot is an example of an automatic process, which is a task performed with minimal conscious effort once the skill has become habitual. This contrasts with controlled processes that require full attention. Therefore, the correct option is A.
Step-by-step explanation:
Driving a car along a familiar route while listening to the radio or thinking of something else is an example of an automatic process. This kind of task is performed with little conscious awareness and effort once the skills become habitual. Conversely, a controlled process is an activity that requires full attention, like navigating an unfamiliar route. The autonomic nervous system, specifically the somatic nervous system, may control some unconscious movements, but typically those are reflexes, not tasks like driving. Driving on autopilot demonstrates the remarkable ability of the human brain to perform complex tasks without deep concentration.
