Comprehensive and Detailed In-Depth Explanation:

The data scientist requires permissions for Einstein Studio (model management) and Prompt Builder (template creation). Note: "Einstein Studio" may be a misnomer for Data Cloud’s model management or a related tool, but we’ll interpret based on context. Let’s evaluate.

Option A: Prompt Template Manager and Prompt Template UserThere’s no distinct "Prompt Template Manager" or "Prompt Template User" permission set in Salesforce—Prompt Builder access is typically via "Einstein Generative AI User" or similar. This option lacks coverage for Einstein Studio/Data Cloud, making it incorrect.

Option B: Data Cloud Admin and Prompt Template ManagerThe "Data Cloud Admin" permission set grants access to manage models in Data Cloud (assumed as Einstein Studio’s context), including viewing and editing AI models. "Prompt Template Manager" isn’t a real set, but Prompt Builder creation is covered by "Einstein Generative AI Admin" or similar admin-level access (assumed intent). This combination approximates the needs, making it the closest correct answer despite naming ambiguity.

Option C: Prompt Template User and Data Cloud Admin"Prompt Template User" isn’t a standard set, and user-level access (e.g., Einstein Generative AI User) typically allows execution, not creation. The data scientist needs to create templates, so this lacks sufficient Prompt Builder rights, making it incorrect.

Why Option B is Correct (with Caveat):

"Data Cloud Admin" covers model management in Data Cloud (likely intended as Einstein Studio), and "Prompt Template Manager" is interpreted as admin-level Prompt Builder access (e.g., Einstein Generative AI Admin). Despite naming inconsistencies, this fits the requirements per Salesforce permissions structure.
