Allylic and benzylic? (Qvault OChem)

The following carbocation is

A: Primary benzylic

B: Allylic

C: Secondary

D: Secondary benzylic

E: Benzylic

Explanation
This is a secondary benzylic carbocation. It is adjacent to a benzene ring and attached to an additional carbon. Because it is a benzylic carbocation, the positive charge can be distributed throughout the ring. The term benzylic generally refers to any substituent, charge, or electron that is on a carbon that is directly attached to a benzene ring. Allylic refers to any substituent, charge, or electron that is on a carbon directly attached to a carbon-carbon double bond.

I'm not understanding how there is only 1 correct answer here. Can't this carbon be considered allylic, benzylic and secondary benzylic? I can see how D is better than E, but not B.
Thanks in advanced!

It's only allylic if it doesn't contain a benzene ring. Here's an example of allylic:

whenever there's an "allylic" benzene its called benzylic

Well it's not allylic because the double bond you see in the ring is not a complete double bond. It's more of a 1.5 bond because the electrons are shared equally throughout the ring. For it to by allylic the C would have to be attached to a permanent C=C as in C-C=C.

Edit: ^^^^ ixyz's link above explains it perfectly.
