Explanation:

- Primary, direct cooperation: This occurs in simpler societies where interactions are personal and face-to-face, like in families or small communities.

- Secondary, indirect cooperation: Typical of modern societies, this involves impersonal, often mediated interactions, such as through institutions or technology. It allows for large-scale organization.

- Primary, direct, indirect cooperation: This combination implies direct personal interactions mixed with indirect methods, which is uncommon in large societies.

- Primary, Secondary, direct, Indirect cooperation: This involves a mix of personal and impersonal, direct and mediated cooperation. It is overly broad and complex.

Option 2: Secondary, Indirect is the right choice for modern complex societies due to their reliance on structured, mediated interactions.
