C Correct answer
Explanation

DBD (Database Descriptor) is created through a process called DBDGEN, which compiles DBD source statements into a usable database descriptor. Each database has exactly one DBD, and it is essential for DL/I (Data Language/I) operations. The statement 'multiple DBDs for each database' is false, and DBDs are required by DL/I, not unusable.
