In a Salesforce CPQ scoping session, the first documentation created is the Business Process Map, because:

It defines the customer’s selling, quoting, approval, pricing, contracting, renewal, and ordering processes.

It ensures all stakeholders are aligned on “how the business works now” before CPQ design begins.

Only after processes are mapped can product structure, order management, and quote document needs be designed.

Salesforce Revenue Cloud methodology always starts with:

Business Process Documentation → Requirements → Solution Design

Thus C is correct.
