Answer 1

(4)

Explanation:

Population density is the number of individuals of a particular species living per unit area or volume at a given time. It is not specifically calculated for an area of 100 square kilometres per year. Therefore, the Assertion (A) is false.

Population density refers to the number of individuals of one particular species, not all living organisms of different species present in an area. Therefore, the Reason (R) is also false.

Hence, both A and R are false.
