The question seems to be asking about the type of data storage solution that is specifically tailored for a particular line of business. Let's analyze the options provided:

1. Enterprise Data Warehouse (EDW): This is a centralized repository of integrated data from multiple sources. It is designed for analysis and reporting across the organization but is not limited to a specific line of business.

2. Operational Data Store (ODS): This is used for operational reporting and is a type of database designed to integrate data from multiple sources for short-term decision-making but typically does not focus on a particular line of business.

3. Data Mart: This is a subset of a data warehouse, often focused on a particular area or department within an organization. Data marts are designed for specific business lines, making them suitable for targeted analysis.

4. Data Lake: This is a centralized repository that allows you to store all your structured and unstructured data at any scale. Data lakes can serve multiple purposes and are not restricted to a particular line of business.

The correct choice is c. Data Mart, as it is specifically designed for a particular line of business.
