The number of years the average newborn in a particular population group is likely to live is called what?

Explanation:
The key idea is life expectancy at birth—the average number of years a newborn is expected to live given current mortality rates. This directly matches the description of the average newborn in a population group and what they are likely to live on average. It’s different from the maximum life span, which refers to the oldest ages reached, and from terms like expected longevity, which aren’t standard measures. So the option that conveys the average number of years a newborn can expect to live best fits the concept.
