{'glucose': [8, 0, 3, 5], 'excess glucose': [0, 0, 1, 0], 'glycogen': [1, 0, 0, 0], 'liver': [2, 0, 2, 2], 'blood stream': [1, 0, 1, 1]}

The correct answer is option 1: Both A and R are true and R is the correct explanation of A.

Explanation:

Assertion (A) states that the liver regulates the level of glucose in the bloodstream. This is true. The liver plays a crucial role in maintaining blood glucose levels by storing glucose as glycogen when it is in excess and releasing it when blood glucose levels are low.

Reason (R) states that excess glucose is stored in the liver as glycogen. This is also true. When there is an excess of glucose in the body, the liver converts it into glycogen and stores it for later use. This stored glycogen can be broken down into glucose as needed and released into the bloodstream to maintain steady blood glucose levels.

Therefore, both the assertion and the reason are true, and the reason correctly explains why the liver regulates blood glucose levels. There is a cause-and-effect relationship between the liver storing excess glucose as glycogen and its role in regulating blood glucose levels.
