Which of the following statements describing a difference between transformations and actions is incorrect?

Question

Options

• AThere are wide and narrow transformations but there are not wide and narrow actions.
• BTransformations do not trigger execution while actions do trigger execution.
• CTransformations work on DataFrames/Datasets while actions are reserved for native language
• DSome actions can be used to return data objects in a format native to the programming language
• ETransformations are typically logic operations while actions are typically focused on returning

• C

Explanation

Choice C is incorrect because actions also operate on DataFrames/Datasets - they are not 'reserved for native language.' Actions like count(), collect(), show(), and take() are called on DataFrames and Datasets; they trigger execution of the DAG and may return results in native language types (e.g., a Python list). The other statements are all correct: transformations are lazy and do not trigger execution; only transformations are classified as wide or narrow; and actions can return native language objects.
