Final answer:
The social convoy theory posits that we rely on friends and family mainly for social support, assistance, and well-being, rather than c. financial support, which is not a central aspect of the theory.
Step-by-step explanation:
According to the social convoy theory, we rely on our close friends and family for a variety of supports. These include social support, such as advice, guidance, encouragement, and emotional comfort; and assistance in managing life challenges. We also derive a sense of well-being from these relationships. However, the primary focus of social convoy theory is not financial support; while it may be a part of the tangible assistance received from friends and family, it is not a central tenet of the theory itself. The main premise is that our friends and family act as a convoy, providing emotional and practical support as we navigate through life's journey.
