The correct answer is B) proximity; the mere exposure effect.
Lina finds Shad, who is in her book club that meets twice a week, very attractive. Lina might have developed interests in Shad because of proximity, which is based on the principle of the mere exposure effect.
People develop some kind of attraction due to factors such as proximity and similarity. If they spend time together on a daily or weekly basis, they tend to develop feelings. As is the case of Lina that finds Shad very attractive. Trough the mere exposure effect, Linda is developing more feelings every time she is in contact with Shad. This effect causes people to create more preference as long is in permanent contact with other people or experiences.
