A,B,C Correct answer
Explanation

The HISTOGRAM statement in Natural/Adabas is specifically designed to read database fields that are defined as Descriptor fields. This includes regular Descriptors, Super Descriptors (which combine multiple descriptor fields), and Sub Descriptors (which are subsets of descriptor fields). Option D is incorrect because HISTOGRAM cannot be used on arbitrary columns - only on fields explicitly defined as descriptors in the Adabas schema.
