Consider a TCP connection in a state where there are no outstanding ACKs. The sender sends two segments back to back. The sequence numbers of the first and second segments are $230$ and $290$ respectively. The first segment was lost, but the second segment was received correctly by the receiver. Let X be the amount of data carried in the first segment $($in bytes$),$ and Y be the ACK number sent by the receiver. The values of X and Y $($in that order$)$ are A $60$ and $290$ B $61$ and $231$ C $61$ and $291$ D $60$ and $230$
