If a network has a throughput bottleneck, does it matter whether the slow link comes before or after?
For example:
c wants to send something to h.
the bottleneck is on h's side. What throughput speed will the red arrow have? 200 or 100?
The question is about throughput only. Meaning we neglect the router's buffer and processing (little queuing delay, processing delay and also transmission delay).

No it doesn't, Only matters when destination is before or after that bottleneck link.
Yes it will be bottle necked at 100mbps. So bottleneck throughput speed would be of the lowest throughput link between h and c. So this bottleneck throughput will be applicable when the packet is sent from h to c also.
Hope this helps!
