I believe the correct answer should be C, but there is a typo in the answer. Instead of allowed, it should say blocked. Basing my reply on other dumps with this question.
Apple Facetime is specifically under the category VOIP
The “excessive bandwidth ‘Facetime’” says specifically “Social media”.
Fortigate Security 730 pg 446 shows the order of progression.
1. Filter Overrides
2. Application Overrides
3. Categories
First - (Priority 1 - Excessive Bandwidth) Apple Facetime is viewed as Apple VOIP so it passes because it does not meet the criteria (Facetime – Social.Media)
Second - (Priority 2 - Apple Filter) Facetime – VOIP is allowed to pass through the Monitor Action.
Third – Category view for VOIP allows traffic to pass through the monitor action.
But overall - because "the priority in which application and filter overrides are placed takes precedence", the traffic is allowed to pass because it does not match the category assigned.
The reality is that the question is wrong.
Facetime is only in Application Control as "VoIP" not as "Social.Media"

The answer "C" is badly written. The real Answer is " Apple FaceTime will be blocked, Based on the Excessive-Bandwith filter configuration"
So the Right Asnwer is C
A
FaceTime is categorize to VoIP
The service MATCH "FaceTime VoIP" which is ALLOW on Apple Filter
And DON'T MATCH "FaceTime Social Media" which is BLOCK on Excessice-Bandwidth
Ans is C
Options should be
C. Apple FaceTime will be blocked, based on the Excessive-Bandwidth filter configuration.
Explanation:
Facetime belongs to VoIP category which is monitored here and therefore should be allowed, however, because of the behavior of the facetime "Excessive-Bandwidth", the custom filter Excessive-Bandwidth will block Facetime and the lookup won't continue to the second filter.
In FortiGate_Security_6.4_Study_Guide p439 Facetime appears as Voip in Excessive Bandwidth filter, so not sure if the fact that here it appears as social media in the question is in order to make it more tricky, or if its a mistake when the question was formulated.
I dont get the fact that Facetime appears with 2 different categories. In Excessive bandwidth it is shown as Social media category, but in Apple filter and Application category it appears as Voip category...So if Facetime would appear as Voip in ExcBan, then it would be blocked? is it changeble the category in the ExcBan?
