Explanation

Cross-Device ID is correct for customer_id because this identity type is designed for persistent identifiers - like CRM IDs or loyalty numbers - that follow a person across multiple devices and sessions, which is exactly the role a customer ID plays. Option A (Person ID) is incorrect because "Person ID" is not a standard identity namespace type in Adobe Experience Platform's identity service taxonomy. Option B (Cookie ID) is wrong because cookies are session/browser-bound and represent temporary, device-specific sessions - not a stable customer identifier. Option D (Device ID) is wrong because device IDs are tied to hardware (e.g., IDFA, GAID), not to a customer account that persists across devices. Memory tip: Think "customer = cross-device" - a customer_id travels with the person, not any single browser or device, just as "cross-device" implies spanning beyond any one endpoint.
