Final answer:
The aspect not included in Sternberg's theory of love is 'attachment'; the three components are intimacy, passion, and commitment. Romantic love is defined by passion and intimacy but no commitment.
Step-by-step explanation:
The item that is NOT one of the aspects of love in Sternberg's theory of love is C. attachment. According to Sternberg's triangular theory of love, the three components are intimacy, passion, and commitment.
As for the type of love that is defined by passion and intimacy but no commitment, it is referred to as romantic love. This form of love is typically characterized by strong emotional and physical connection between two people, but without the long-term pledge to stay together.
Other examples of relationships that fit the different types of love mentioned in Sternberg's theory could include friendships for liking, which involves intimacy without passion or commitment; a whirlwind romance for infatuation, which involves passion without intimacy or commitment; and a marriage of convenience for empty love, which involves commitment without passion or intimacy.
