Final answer:
Interpersonal attraction involves individuals forming close bonds based on shared interests, need for reciprocity, and physical attractiveness. The similarity between individuals and the matching hypothesis also significantly influence whom people choose to form relationships with. Hence, option (a) is correct.
Step-by-step explanation:
Interpersonal attraction in close relationships involves forms of bonds that are based on several factors, including shared interests and mutual needs. Physical attractiveness plays a role in attraction but is not the sole factor. Equally important is the notion of reciprocity, the give and take in relationships, where we expect to exchange similar levels of self-disclosure and rewards. Such reciprocal interactions help deepen connections.
Furthermore, similarity has a major influence on with whom we form relationships. We tend to be drawn to people who share our attitudes, values, and overall lifestyle, and this homophily makes it easier to form and maintain bonds. Researchers also suggest that individuals tend to select mates who match their level of physical attractiveness and social desirability, known as the matching hypothesis.
All these elements contribute to the complex experience of interpersonal attraction which encompasses intimacy, passion, and commitment in various kinds of relationships.
