Leanna, a bride to be, is glancing over an updated list of the people who will be attending her wedding reception. there actually will be an equal number of people from her family and from her fiancé robert's family. without counting, leanna perceives that more people from family will be in attendance, due to the (a) her; the availability bias(b) her; the conjuction fallcy(c) robert's; the availability bias(d) robert's; the conjuction fallcy

(A) Her; the availability bias

Explanation:

According to my research, I can say that Leanna perceives that more people from her family will be in attendance; due to the availability bias. Availability bias is defined as "mental shortcut that relies on immediate examples that come to a given person's mind when evaluating a specific topic".  This being the case, since Leanna is the one who is perceiving this information we can assume that the first things that come to her mind is all the people from her family since she has more memories of them.
