Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Life expectancy is the average (over the population) total number of years (or days, or hours) that an organism expects to live. It is fundamentally different from life span, which is the maximum time interval that an organism can live. Thus maximum life span is the characteristics of a species whereas life expectancy is the characteristics of a population.
