B. Her sample is a biased one, because her sample was not a random one.

Explanation:

Biased sample: In psychology, the term biased sample refers to the procedure in which a particular group is selected for a statistical survey or study lack random assignment and is not able to represent a population. It occurs because a particular sample being taken for the study isn't representative of a large population.

For any research or study to give valid and unbiased information or result then it should contain random assignment while selecting the sample from a large population.
