D Correct answer
Explanation

When JCLLIB is not coded in the JCL, the system searches the default procedure library SYS1.PROCLIB for cataloged procedures. This is the system-defined default location for JCL procedures. The other options are incorrect - SYS.PROCLIB and SYS.PROCLIB1 don't exist, and SYS1.PROCLIB1 is not the default.

AI explanation

When a JCL doesn't specify a JCLLIB statement, the system falls back to searching the standard system procedure library, SYS1.PROCLIB, for cataloged procedures. The other options are simply typo'd or malformed variants of that library name and don't correspond to any real default search library.
