Which OCI service provides a scalable environment for developers and data scientists to run Apache...

Detailed Answer in Step-by-Step Solution:

Objective: Identify the OCI service for scalable Spark applications.

Evaluate Options:

A: Data Science—ML platform, not Spark-focused.

B: Anomaly Detection—Specific ML service, not general Spark.

C: Data Labeling—Annotation tool, not Spark-related.

D: Data Flow—Managed Spark service for big data.

Reasoning: Data Flow is OCI’s Spark execution engine.

Conclusion: D is correct.

OCI Data Flow “provides a fully managed environment to run Apache Spark applications at scale, ideal for data processing and ML tasks.” Data Science (A) supports Spark in notebooks, but Data Flow (D) is the dedicated, scalable solution—B and C are unrelated.
