Which best describes the ability of client triggers to impact record processing?

The ability of client triggers to impact record processing is best described by the option indicating that they execute during record creation and editing. Client triggers are JavaScript functions that run in the context of the user's browser when interacting with NetSuite forms. This means they can be used to validate data, set default values, or respond to user actions at various points in the lifecycle of a record.

During the creation and editing phases of a record, client triggers provide the flexibility to modify data and enforce business rules dynamically. For example, you might use client scripts to ensure that users enter values in specific fields or to make certain fields required based on the user’s input. By executing during both the initial creation of a record and any subsequent edits, client triggers enhance user experience and data integrity by providing real-time feedback and interactivity.

Other options don't fully capture the functionality of client triggers. Modifying data solely during record view would limit the triggers' usage, while stating they only occur during record submission would overlook their earlier execution during creation and editing. Claiming they cannot change field values would contradict their purpose, which is ultimately to allow for data manipulation and validation based on user actions.
