B. population

Explanation:

In statistics, a sample is a subset of cases or individuals in a population. In various applications, it is important that a sample be representative, and for this a suitable sample technique must be chosen that produces an adequate random sample (a biased sample is obtained whose interest and utility is more limited depending on the degree of biases present).

As a subgroup or representative subset of the population, extracted selected by some sampling method. The sample is always a part of the population. If you have several populations, then you will have several samples. The sample must have all the desired information to be able to extract it, this can only be achieved with a good selection of the sample and a very careful and high quality work in the collection of data.
