The correct option is;

A. The file will not take up as much space on the database

Explanation:

Changing the field size of a field that does not contain data limits the size of taken up by the data values added to the field. The field size for text field determines the disc space that each value of the field allowed to take up by Access

When the field size is changed for fields containing data, the data values in the field that have values higher than the maximum field size are truncated while the field size of subsequent data are limited as stated above.
