What should a consultant recommend?

A customer manually imports records for sending. Each record contains a warehouse ID that is shared between Marketing Cloud and a third-party system. The customer does not have developer resources, but wants to include the warehouse ID in their tracking parameters so that the third-party system can identify the subscriber.

What should a consultant recommend?
A . Use personalization strings created by selecting the data extension.
B. Use AMPscript variables created from each field in the data extension.
C. Use Dynamic Content rules to select a content area for each subscriber.
D. Use Guide Template Language created for each field in the data extension.

Answer: A

Explanation:

Using personalization strings created by selecting the data extension can be used to include the warehouse ID in their tracking parameters so that the third-party system can identify the subscriber. Personalization strings are placeholders that can be inserted into emails or landing pages to display information from data extensions or lists, such as subscriber attributes or custom fields. Personalization strings can also be used as tracking parameters in links or image tags.
