Correct Answer: C

• Option A (Execute the shell script as the Workspace admin): Incorrect. The script's execution time is not influenced by the user's administrative status.
• Option B (Utilize %md to accelerate the script execution): Incorrect. %md is a magic command for Markdown, unrelated to shell script execution speed.
• Option C (Incorporate the shell script as an init script for faster execution): Correct. Using %sh in a Databricks notebook confines execution to the driver node. For broader execution across worker nodes, embedding the script as an init script is essential.
• Option D (Augment the number of worker nodes to enhance script speed): Incorrect. Since %sh commands only utilize the driver node, additional worker nodes won't affect execution speed.
• Option E (Trigger the notebook execution via the Databricks API): Incorrect. The script's speed is independent of the notebook's triggering mechanism.

Additional Information: Init scripts in Databricks can significantly optimize script execution across clusters.
