   A large insurance company is launching a data science project to predict claim fraud. The project has a tight deadline and a limited budget. The team includes a data scientist, a data engineer, a business analyst, and a domain expert from the claims department. During Discovery, the domain expert identifies a critical data source that is not currently accessible and requires a lengthy approval process. The project sponsor wants to keep the project on schedule. What is the best approach?

   • ADelay the project until the data access is approved.
   • BInitiate the approval process and simultaneously explore alternative data sources that may be accessible sooner.
   • CAsk the domain expert to manually extract the data from the source system.
   • DProceed with the accessible data and document the missing data as a limitation.
