1. Salesforce Help, Consumer Goods Cloud Documentation, "Execute a Promotion Check": This document explicitly states the process for a field rep. It notes, "On the Promotion Check page, you can see the promotion description, the products included in the promotion, and the promotion channel." It also instructs, "To capture an image of the promotion, tap [the camera icon]." This directly supports answers A and C.
2. Salesforce Trailhead, "Visit Execution in Consumer Goods Cloud" module, "Perform In-Store Audits" unit: This educational module describes the role of a field rep. In the context of a promotion check, it details the rep's actions: "...he checks whether the NTO branding is visible, the discounted price is correct, and the products are placed on the correct shelves. He also takes a picture of the promotion display." This confirms the ability to view product details (to check placement) and take photos.
