B Correct answer
Explanation

MXIG (or MGIX) is the JCL DD parameter that directs the system to allocate the dataset on the largest available volume. CONTIG requests contiguous space on a single volume but doesn't specify volume size. ROUND rounds up space allocation to track boundaries for efficiency, and RLSE releases unused space at job end.
