Between $\text{B}$ and $\text{C, S}$ is half close and at the label $\text{D, X}=4001, \text{Y}=9501$.

@GO Classes

I think statement III is correct as only Acknowledgment does not consume any sequence number.
So sequence number will remain same as 4000.

Hence, X=4000

So, II and III are correct.

Please check the above @GO Classes. Since only ack the sequence number could remain the same.
