Correct Option: D

Choose the correct answer from the alternatives given.
To which of the following organ/blood is supplied by the internal carotid artery?

  1. Kidney

  2. Liver

  3. Heart

  4. Brain


Correct Option: D
Explanation:

The brain forms only 2% of the body but uses up to 20% of the oxygen. It is given the top priority during the distribution of oxygen-rich blood. The internal carotid arteries and vertebral arteries carry oxygen-rich blood from the heart to the brain. 

So, the correct option is 'Brain'.
