$3\mathrm{.}4-12$ Packet buffering in Go$-$Back$-$N $($more$).$ What are some reasons for not discarding received$-$but$-$ out$-$of$-$sequence packets at the receiver in GBN$?$ Indicate one or more of the following statements that are correct.

Group of answer choices

Even though that packet will be retransmitted, its next retransmission could be corrupted, so don$$t discard a perfectly well$-$received packet, silly!

By not discarding, the receiver can implicitly let the sender know that it $($the sender$)$ does not necessarily have to retransmit that packet.
