Why not AF32 since it's higher then 13 ?

because AF32 is higher priority than AF13. so AF13 is more likely to be dropped because of the '1' and the '3'

In the following example, packets in the AF13 class will be dropped before packets in the AF12 class, which in turn will be dropped before packets in the AF11 class: dP(AF13) >= dP (AF12) >= dP(AF11) https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/qos_dfsrv/configuration/15-mt/qos-dfsrv-15-mt-book/qos-dfsrv.html#GUID-42E30ADD-2C7B-4273-B20D-ACE5182A9314 Correct Answer AF13
