Are you all serious? B is the MOST WRONG option. Column mapping can set a value of parent table field to the filed of sub table, B does it in reverse. And the wording of 'map xxx to xxx' is very confused than 'set xxx to xxx' I refer to AC.

B is trying to map values in Parent from child and it should be the other way. Also, it is saying that A column is using column values (Multiple columns) from the child table, so even if mapping Parent from Child was possible, the types would not match. For D, column types don't match

When you map table columns for a 1:N table relationship certain items of data from the primary table row will be copied into the new related table form to set default values that people can edit before saving. https://learn.microsoft.com/en-us/power-apps/maker/data-platform/map-entity-fields

A and C are the correct option because, If you map to or from a column that isn’t displayed on a form, the mapping won't be done until the column is added to a form. Option C says the the fields on the "Quick Create" & "Main" form.

For me, B is correct but with C I have doubts because it is possible but it is not a certain.

I think it's BC. I guess C means "map the column present in those forms to the other entity". Map relationship is not based on forms but on columns, ok, but I guess they talk about "columns present in those forms"... who knows? Only Microsoft

A and D are not possible. You cannot map a choice value to another choice value as suggested in A. Could there be something wrong with the wording for question B? If it was a choice column the question would make sence.

A is possible "If you need to map choice columns, we recommend you configure both columns to use the same global choice . Otherwise, it can be difficult to keep two separate sets of options synchronized manually. If the integer values for each option aren’t mapped correctly you can introduce problems in your data. More information: Create and edit global choices for Microsoft Dataverse (picklists)"
