A salesperson needs to know which subscription a customer has subscribed to or unsubscribed from when reviewing their account in Sales Cloud…

B. Creating a custom preference center that updates the records in Sales Cloud can help meet the requirements by allowing customers to manage their subscription p

and opt-in or opt-out

of different email lists or publications. This can also provide more granular control over the data

synchronization between Sales Cloud and Marketing Cloud. D. Implementing the Marketing Cloud

Connector can help meet the requirements by enabling bi-directional data integration between Sales

Cloud and Marketing Cloud. This can also allow Marketing Cloud to honor the unsubscribe status of

contacts or leads in Sales Cloud when sending emails. Reference:
