B.

and all other 802.1D port states remain the same in 802.1w.

C.
The 802.1 D port states Disabled, Blocking, and Listening have become the 802.1w port state
Discarding, and all other 802.1D port states remain the same in 802.1w.

D.
The 802.1 D port states Disabled, Blocking, and Listening have been removed completely from
802.1w (there is no corresponding port state), and all other 802.1 D port states remain the same in
802.1w. )

E.
The 802.1 D port state Disabled has been removed from 802.1w, and the 802.1 D port states
