The answer is the last one: salivary reflex.

Explanation for each option:

  1. Plantar reflex: This is a somatic reflex, not an autonomic reflex. It involves the stimulation of the sole of the foot and is used to assess the integrity of the spinal cord and peripheral nervous system.

  2. Gag reflex: This is also a somatic reflex. It involves the contraction of the throat muscles when the back of the throat is touched, and it is primarily mediated by the glossopharyngeal and vagus nerves.

  3. Crossed-extensor reflex: This is a somatic reflex as well. It involves the extension of the opposite limb when one limb is withdrawn from a painful stimulus, helping to maintain balance.

  4. Salivary reflex: This is an autonomic reflex. It involves the secretion of saliva in response to stimuli such as the sight, smell, or thought of food, and is controlled by the autonomic nervous system.

In summary, the salivary reflex is the correct example of an autonomic reflex among the options provided.
