Answer: Ask the other team to grant your default App Engine Service account the role of BigQuery Data Viewer.
The correct answer is B: Ask the other team to grant your default App Engine Service account the role of BigQuery Data Viewer. The BigQuery Data Viewer role provides permissions to read data and metadata from datasets and tables, which aligns with the requirement of your application needing to read data from a BigQuery dataset in another project. The BigQuery Job User role (option A) allows running jobs, including queries, but does not grant permissions to read data from tables or datasets.
