Which option allows you to import data while keeping the field information unchanged?

Selecting the option that states 'Do not change any field information' is correct because it explicitly instructs the system to maintain the existing structure and characteristics of the fields in the database. When importing data, it's crucial to ensure that the integrity and format of the existing fields are preserved to avoid any issues with data compatibility or loss of information.

This option directly addresses the need to keep field information unchanged, which is essential for maintaining data consistency, especially when merging new data into an established database structure. By choosing this option, users can confidently bring in new data without worrying about unintended modifications to the existing fields.

The other options may involve some degree of modification or adjustment to the field information, which goes against the requirement of keeping it unchanged. Therefore, this choice is the most appropriate for ensuring that the original field definitions remain intact during the import process.
