B) They are using the representativeness heuristic.

A) The anchoring effect can lead to gender bias.

Explanation:

this is a human tendency where people rely on a trait  of what things used to be in the past. In most cases people in the society think that women cannot be assertive,ambitious or become leaders because they are only for the household .the trait is bound to the society even other women find it very hard to stand up for themselves.they think that male student are the only ones who are ambitious and athletic because of the masculine part.  

the density would be a smaller number.
