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

The correct answer is A. Configure Campaign Interactions and Campaign statistics.

The option text appears to contain an OCR/wording issue. The intended Salesforce feature is Campaign Hierarchies and Campaign statistics. For advertising ROI, Salesforce Campaigns are the correct feature because Campaign ROI reports calculate return on investment using campaign cost and won opportunity value. Salesforce also states that campaign hierarchy metrics roll up from child campaigns to parent campaigns, which helps analyze campaign performance across related marketing efforts.

B is incorrect because Account interactions and roll-up summary fields are not the standard marketing ROI solution.

C is incorrect because changing the whole org to a public security model is unnecessary.

D is incorrect because an opportunity pipeline report alone does not provide campaign ROI analysis.
