What is the difference between AAL5 SNAP and AAL5 MUX virtual circuits?

A.
AAL5 SNAP is used to carry IP packets embedded in PPP encapsulation and AAL5 MUX is used to carry raw IP data.

B.
SNAP allows multiplexing of multiple protocols over a single VC, while AAL5 MUX can carry only one protocol per VC.

C.
SNAP VCs define real time data and MUX VC defines mixed (real time and non real time) data.

D.
SNAP VCs are used inside public carrier network while MUX VCs are used on the edge.

E.
None of the above
