You are a consultant on an SAP S/4HANA Cloud greenfield project.

From the “Managing Clean Core for SAP S/4HANA Cloud” learning journey on learning.sap.com, the recommended tool (among the options listed) for analyzing the current IT landscape—especially in a greenfield, clean-core journey—is:

Therefore, the correct answer from that source is:

•C. SAP Best Practices

(It appears that only one of the given options is supported in the SAP learning content for this scenario.)
