To group measures in the Fields pane, although it sounds technically credible, it does not align with how DAX functions propagate context in this scenario.

To improve query performance, although it sounds technically credible, it does not align with how DAX functions propagate context in this scenario.

A calculation pattern that is useful for measures in general but does not satisfy the specific context transition requirement here

To apply common calculations (like YTD, PY) to multiple measures without duplicating code

To create calculated tables, however, this wording confuses row context, filter context, or evaluation timing and therefore misses the exact DAX behavior being tested.
