Ah, the old master-detail dilemma. I reckon it's gotta be B. Can't be messing with those roll-up summary fields, am I right?

I think you're onto something with that. Messing with roll-up summary fields can cause issues.

Haha, you know what they say, 'If it ain't broke, don't fix it!' Looks like the UC admin tried to change something that wasn't meant to be changed. I'd go with B on this one.

Hmm, I'm not so sure. Maybe it's C - the Account object doesn't allow changing the field type for a custom field, so they couldn't convert the relationship.

I'm not sure, but option C also seems like a valid reason. The Account object might not allow changing a field type for a custom field.

I think the answer is B. The Account object has a roll up summary field on the Vendor object, so the master-detail relationship can't be changed to a lookup.
