Explanation:

[#1]

To define "population" in statistics, we recall that a population is the entire group of interest (people, objects, entities) from which data is collected. Option A describes a sample (a subset), option C is a parameter (calculated from population), option D is a statistic (calculated from sample). So option B matches the definition of population.

For "sample", it is a subset of the population. Option B is population, option C is parameter, option D is statistic. Option A defines a sample as a part of the entire group.

A "statistic" is a value calculated from a sample (to estimate a population parameter). Option A is sample, option B is population, option C is parameter. So option D defines statistic.

Answer:

B. An entire group of people, objects, or entities.
