  1. Medulla oblongata

  2. Cerebellum

  3. Cerebral cortex

  4. Thalamus


Correct Option: B

Which one of the following is the example of action of autonomous nervous system?

  1. Knee-jerk response

  2. Pupillary reflex

  3. Swallowing of food

  4. Peristalsis of the intestines


Correct Option: D
Explanation:

Peristalsis of the intestines is the example of the action of the autonomous nervous system. The organs of our body (viscera), such as the heart, intestines and stomach, are regulated by a branch of the nervous system known as the autonomic nervous system. It consists of autonomic neurons that conduct impulses from the central nervous system (brain and/or spinal cord) to glands, smooth muscle and cardiac muscle. ANS neurons are responsible for regulating the secretions of certain glands (i.e., salivary glands) and the regulation of heart rate and peristalsis (contraction of smooth muscle in the digestive tract), among other functions. So, the correct answer is option D.
