Answer is 15.

As given, this is sliding window protocol so,in case consider Selective repeat:
 Sender window size = Receiver window size

and
Sender window size + Receiver window size = sequence numbering(24)

Let window size is N.
N+N= 24

N=23
window size=8.
If we consider GBN then the max window size (16-1) =15

So Max window size =15
