Universal Containers wants to understand return on investment for the latest advertising buy.

The correct answer is C. Configure Campaign Hierarchies and Campaign statistics.

To understand return on investment for an advertising buy, Universal Containers should use Salesforce Campaigns, especially Campaign Hierarchies and campaign reporting/statistics. Salesforce campaign hierarchy documentation explains that child campaign metrics roll up to the parent campaign, and Salesforce campaign reports can include campaign-hierarchy statistics for aggregate values.

The private security model does not require changing the whole org to public. The business need is marketing ROI tracking, so Campaigns are the correct feature.

A is incorrect because an opportunity pipeline report does not directly track advertising campaign ROI.

B is incorrect because Account Hierarchies and roll-up summaries are not the standard solution for campaign ROI.

D is incorrect because changing to a public security model is unnecessary and weakens data security.
