To answer this question, you need to understand the internal scripting language of the DataStage Engine.

Option A) Shell Script - This option is incorrect because Shell Script is not the internal scripting language of the DataStage Engine. Shell Script is a scripting language commonly used for automating tasks in Unix-based operating systems.

Option B) OSH - This option is correct. OSH (Orchestrate Shell) is the internal scripting language of the DataStage Engine. It is used to define and control the execution of DataStage jobs and perform various data integration tasks.

Option C) Scriptella - This option is incorrect. Scriptella is an open-source ETL (Extract, Transform, Load) and script execution framework, but it is not the internal scripting language of the DataStage Engine.

Option D) All the above - This option is incorrect because only option B (OSH) is the correct internal scripting language of the DataStage Engine.

The correct answer is B) OSH. This option is correct because OSH is the internal scripting language specifically designed for the DataStage Engine.
