Could it be so that it's only the localizer that is on the "maximum safe deflection"? If the question is "which diagram shows the maximum safe deflection", it doesn't really mean that both the LOC and the GS need to be at the max. As long as one of them is at it's maximum permitted deflection and all the other diagrams are showing a lesser degree of deflection, this will make the given answer correct. Do you understand what I'm trying to get at or am I just making it worse. You've got the right idea, but it's a matter of question technique...
