No!
Go back n arq doesn’t support individual acknowledgement because it follows cumulative acknowledgement instead of independent acknowledgement.
In Go back n, the window has to be retransmit in case of lose of a single packet which clearly determines that acknowledgement is sent for the whole window not for a single packet which means this protocol follows cumulative acknowledgement
selective repeat follows independent acknowledgement.
go back n arq sends automatically packet after timeout if the acknowledgement of the packet didn’t reached the sender.
