d. A is 1, C is 1 and RII is 1
The A, or Address Recognized; and C, or Frame Copied; bits are
contained within the Frame Status byte in a Token-Ring frame. When a
frame is copied by a source-route bridge to be put out onto another
ring, the bridge sets these bits, much as if it were actually the
destination station. Additionally, the Routing Information Indicator
(RII) in the source address field is set to 1 (one) by the source device.
