To meet the Chief Marketing Officer's requirements, the administrator must configure three core elements. First, to "award points... that can be redeemed," a non-qualifying currency is required, as these points are spendable. Second, to "gamify customers that spend the most," a tier system is necessary to segment members and provide exclusive benefits. Tier progression is tracked using a qualifying currency or metric. Therefore, setting up both currency types (Option A) is foundational. Finally, promotions (Option E) are the mechanism used to define the rules for how members earn these points, directly fulfilling the "award points" requirement. These three elements (currencies, tiers, and promotions) form the essential structure of the requested loyalty program.

B. Set up one qualifying currency: This is insufficient. It only addresses tier progression and omits the non-qualifying, redeemable currency required for members to redeem points for products.

D. Set up vouchers for specific products: This is a type of reward or benefit, not a foundational program element. The core requirement is to award redeemable points; vouchers are just one possible redemption option.

1. Salesforce Help, Topic: Define Your Loyalty Program's Currencies: "You can define two types of currencies for your loyalty program: non-qualifying and qualifying. Non-qualifying points are redeemable for rewards. Qualifying points help members upgrade to a higher tier and aren't redeemable." This documentation supports the need for both currency types as described in option A to fulfill both of the CMO's requests.

2. Salesforce Help, Topic: Define Your Loyalty Program's Tiers: "Tiers help you classify members in a loyalty program based on their engagement with your brand. You can create tiers and define the benefits that members of each tier are eligible for." This directly supports the configuration of a tier system (Option C) for gamification and exclusive benefits.

3. Salesforce Help, Topic: Promotions in Loyalty Management: "Use promotions to engage with your loyalty program members. You can set up different types of promotions to credit points, issue vouchers, or provide other benefits to your members." This confirms that promotions (Option E) are the correct mechanism for awarding points to customers.
