D Correct answer
Explanation

A PSB (Program Specification Block) must contain at least one PCB (Program Communication Block) to define database access, but there is no technical upper limit on how many PCBs it can contain. The limit is practical rather than architectural - you define as many PCBs as your program needs to access different databases or views.
