C is the main culprit for packet loss, no doubt!

I think B) minimum receive window sizes could also be a factor.

I'm going with C. Congestion is the network problem that can cause all those issues.

C is the way to go. Gotta watch out for that network congestion, am I right?

Haha, I bet the answer is D. An overloaded TCP connection table would really throttle things down.

Definitely C. Congestion is the biggest culprit for packet loss and throughput issues.

I feel like smaller packet sizes could lead to issues too, but congestion seems like the most obvious answer here.

I’m a bit confused about minimum receive window sizes. Could they also contribute to throttling, or is that more about the amount of data being sent?

I remember practicing a question about TCP connections and how they can get overloaded, but I feel like congestion is more directly related to packet loss.

I think congestion along a network path is definitely a major factor for packet loss, but I'm not entirely sure if it's the only one.

I'm a bit confused on this one. I was thinking it might be A - smaller packet sizes, but now I'm not so sure. Guess I'll have to think it through more carefully.

I'm leaning towards B - minimum receive window sizes. That could limit the throughput and cause queuing, right? But C also makes sense to me.

C) congestion along a network path seems like the correct answer here.

Definitely C. Congestion is the main culprit when it comes to network performance problems like that. The other options don't seem as directly related.
