Final answer:
Closeness and honesty are feelings closely involved with intimacy, which is a component of Sternberg's triangular theory of love. Romantic love features passion and intimacy, but lacks commitment.
Step-by-step explanation:
The feelings closely involved with intimacy are essentially about closeness, trust, and the sharing of intimate thoughts and emotions between individuals. In the context of Sternberg's triangular theory of love, intimacy is one of the three fundamental components, alongside passion and commitment. When considering the options provided in your question, all of them could be aspects of intimacy, but closeness and honesty are the ones most directly involved. Frankness, while also a part of honest communication, is not typically used as a defining feature of intimacy. Therefore, the most accurate options reflecting feelings of intimacy would be 1) closeness and 2) honesty.
According to Sternberg's triangular theory of love, the kind of love that is defined by having passion and intimacy but no commitment is known as romantic love. Examples of relationships that might exhibit romantic love include those that are intense and emotionally intimate but are not necessarily long-term or may not involve a deliberate decision to stay with the partner regardless of what the future might bring.
