What type of field stores information about customer details related to events?

The correct answer is A. An E Field is specifically designed to store structured information related to customer details, including pertinent data linked to events. This type of field is prevalent in systems that manage customer interactions and experience data, allowing organizations to effectively capture and analyze information such as customer demographics, preferences, and historical interactions specific to events. By utilizing E Fields, companies can create a more comprehensive view of the customer experience, facilitating targeted engagement and informed decision-making based on the captured event data.

The other options do not represent fields typically associated with event-related customer details in the context of customer experience management systems like Medallia. Different types of fields may have distinct purposes, but the focus of this question pertains to capturing essential customer data in relation to events, which the E Field fulfills effectively.
