Who provides informal support?

The correct answer emphasizes the role that friends, relatives, and neighbors play in providing informal support. Informal support refers to the assistance that is offered by people in an individual's social circle rather than by trained professionals or formal organizations. This type of support is characterized by personal relationships and the emotional and practical help that these individuals can provide, such as companionship, advice, or help with daily tasks.

In contrast, the other options refer to formal or organized sources of support. Professionals and counselors offer expert guidance usually within a structured environment, while nonprofit organizations provide services through established programs. Community leaders, although influential, often operate within formal roles and structures in community governance or organization. Therefore, while all these groups may contribute to an individual's overall support system, it is friends, relatives, and neighbors who are the primary sources of informal, personal support.
