I thought throughput was related to frame size, but I’m confused about whether it’s halved or if it stays the same.

I feel like the buffer credits play a role here, so maybe D is the right answer since adjustments might be needed for optimal throughput.

I remember a similar question where we discussed how frame size impacts throughput, but I can't recall the exact relationship.

I think if the frame size doubles, the throughput might be affected, but I'm not sure if it halves or stays the same.
