B
Correct answer
Explanation
The .NTF extension specifically stands for 'Notes Template Facility' and is used for template database files in Lotus Notes/Domino. Templates serve as blueprints for creating new databases - they contain design elements but no user data. Option A is incorrect because NSF refers to regular storage facility databases, not templates. NTF files are the master templates from which NSF databases are created.
