FECN=Bit set by a frame relay network to inform the DTE receiving the frame
that congestion was experienced in the path from source to dest.DTE
receiving frame with the FECN bit set can request that higher level
protocols take flow control action,as appropriate.
Therefore A would be the coreect ans.
