What personality type is characterized by relaxed, patient, and easygoing behavior?

The correct choice is indeed Type B personality. This personality type is associated with an easygoing, relaxed demeanor, where individuals tend to be more tolerant, less competitive, and more patient compared to their Type A counterparts. People with a Type B personality are not typically driven by stress or urgency and often take life at a more leisurely pace, which contributes to their overall tranquility.

Type B individuals are often more adaptable in social situations and are generally more content and easy to get along with. They may manage stress more effectively because they are not as prone to the urgency and time pressures that characterize Type A personalities. This definition and understanding align closely with the traits described for Type B personalities.
