Automatic processes

A) require lower levels of attention than controlled processes.
B) need more conscious effort than controlled processes.
C) interfere with other ongoing activities.
D) are unconscious behaviors.

Automatic processes are those that do not require high levels of attention or conscious effort. They are often triggered by environmental cues or habits, and can be performed without much thought or attention. Controlled processes, on the other hand, require conscious effort and attention, and can interfere with other ongoing activities. Therefore, option A is the best choice.
