Final answer:
The task not considered a primary function of the nervous system is affecting glandular output; primary functions include sensing the world, integrating information, and stimulating motor responses.
Step-by-step explanation:
The option that is not considered a general primary task of the nervous system is c) affecting glandular output. The primary tasks of the nervous system are sensing the world by receiving information about changes from homeostasis or external events, known as stimuli; integrating information which involves combining sensory perceptions with cognitive functions such as memories, learning, and emotion; and stimulating a motor/cellular response by transmitting signals from the brain to the rest of the body. Affecting glandular output falls under the endocrine system's function rather than the general primary tasks of the nervous system.
