Final answer:
The question addresses changing the Field Size of a database field, specifically in the context of a 'State' field within a 'Clients' table. The proper method is to make this change in Datasheet View directly and confirm despite potential data loss warnings. So the correct answer is option C.
Step-by-step explanation:
The subject of this question pertains to the procedures for modifying a database field's properties, specifically the Field Size of a column (or 'field') in a database table within a database management system (DBMS). The question asks for confirmation of the process to change the field size of the 'State' field in a table called 'Clients'.
The correct procedure to accomplish this task would be answer (c): In Datasheet View, directly change the Field Size of the State field to "2" and click YES when warned about potential data loss. This action modifies the field size and this change will be applied immediately to the database and will persist even if there is a data loss warning.
Methods like executing an SQL query or making changes via Design View would also change the field size but usually offer the chance to review changes before saving them. Exporting the table, editing it in a spreadsheet program, and re-importing it would be a less common approach for this specific type of change and is not mentioned as an option in the correct answer.
