Explanation:

- Life expectancy is an indicator of the average number of years a person is expected to live based on current mortality trends.

- Option 1: 68.3 years (This was the approximate life expectancy in India a few years ago.)

- Option 2: 71.2 years (Recent estimates suggest life expectancy in India is closer to this figure.)

- Option 3: 75.5 years (Higher than current estimates for India; more typical for some developed countries.)

- Option 4: 65.3 years (Reflects past data but not current estimates for India.)

- The correct answer is: Option 2: 71.2 years
