To fully qualify a GU (Get Unique) call in IMS, you must include SSAs (Segment Search Arguments) for all segments in the path from the root to the target segment. This tells IMS exactly which segment occurrence to retrieve. Option A is wrong because status code is returned, not included. Option B is incorrect because SSBs don't exist in this context. Option C is wrong because a get call isn't required before a get call. Option E is incorrect because segment name is in the SSA itself.
