Answer:
The family is the most important institution, because ensure the perpetuation of the society from a biological and social perspective, we could say that's the most important role, which implies other subsequent roles. In consequence, families have other roles, not only maintain a society, but to build it with specific values.
Families have roles like to give support other family members, develop life skills, provision of resources, management of the family itself as a social institution. As you can see, family has several roles, not a unique one, which is also complemented by individual roles (family members). So, we could define the role of the family as multidimensional.
In addition, from a social perspective, family members develop their individual roles inside the family environment, which means that they often perform differently in other contexts, influencing others in a different way.
Therefore, the correct answer is "all of the above", because all those statements are part of the family roles.
