Option: B is the right choice. B. Every member of the boys' basketball team. A biased sample is one that isn't random, as it indicates a preference in selection. A.) Every tenth boy from the school’s phone directory is random, giving every student an equal chance of selection, thus, it’s not biased. C.) Every boy in randomly chosen ninth-, tenth-, eleventh-, and twelfth-grade gym classes is also random, making this option incorrect. D.) Every fifth boy entering the school in the morning has equal selection probability as well, so it doesn't represent bias. B.) Every member of the boys' basketball team constitutes a biased sample, since they tend to be taller, leading to larger shoe sizes. Thus, it doesn't represent the average shoe size of male students in the school.

B. every member of the boys' basketball team, as basketball players are typically taller, resulting in larger feet which do not accurately reflect the average shoe size of the male students.
