Which of the following is not a role of a Data Scientist?

Creating SQL-based dashboards and generating routine business reports (answering "what happened?") is the role of a Data Analyst, not a Data Scientist. A Data Analyst queries structured data using SQL, builds dashboards in Power BI or Tableau, and tracks KPIs like branch performance metrics.  A Data Scientist's roles include:  • building ML/statistical predictive models (option A) • working with structured and unstructured data using Python/R (option B) • answering forward-looking questions like "what will happen?" and "why?" (option C) • building domain-specific models like credit scoring and fraud detection in banking (option E).  Other related roles:  • Data Engineer builds data pipelines and infrastructure • ML Engineer deploys and scales models in production.
