The system admin at a nonprofit has set up automated soft credits to grant to...

In NPSP, soft credits are fundamentally based on the Opportunity Contact Role (OCR) object. Even if "Partial Soft Credits" are used for splitting a gift, the primary mechanism for attributing a "Solicitor" to a donation is assigning them a specific role on the Opportunity.

Reporting Logic:

The Junction: The Opportunity Contact Role acts as the bridge between the Opportunity (the donation) and the Contact (the solicitor).

Standard Report Type: The standard report type Opportunities with Contact Roles allows the user to see the donor (the Account) and all related contacts who have a role on that gift.

Filtering: The Admin can filter this report by the "Role" field (e.g., Role EQUALS Solicitor). This surfaces exactly who the solicitor was for every donor's transaction.

Why other options are incorrect:

Option D: Partial Soft Credits is a more complex object used when multiple people get different dollar amounts of credit for a single gift. For a standard report showing "who the solicitor is," the Contact Role is the simpler and more standard starting point.

Option A: Relationships track person-to-person ties (like "Spouse" or "Coworker"), not who influenced a specific financial transaction.

Option B: This focuses on the Household structure rather than the individual donation influence history.
