Interpersonal relationships can be categorized on combinations of three components of love, which are passion, intimacy, and ______.

A) humor
B) reciprocity
C) commitment
D) honesty

Passion and intimacy are important components of love, but without commitment, a relationship may not last. Commitment involves a decision to maintain the relationship and work through challenges, even when the initial passion fades. Humor and honesty can also be important in relationships, but they are not components of love. Reciprocity, or the give-and-take nature of a relationship, is important but is not one of the three components of love in this category.
