Wasted work after timeouts

The edge gives each request 1 s. Service A calls B with a 1 s timeout, and B calls C with a 1 s timeout. Under load, C stays busy with requests the edge already abandoned. What is the best fix?

A.Give each layer a longer timeout than the one above itB.Remove all timeouts so work always completesC.Propagate a deadline so each hop uses only the time remaining, and stop work when it expiresD.Add retries at every layer to make up for timeouts
