Don't pay too much attention to the "correct answer", the "most voted" is much more reliable.

Selected Answer: C
C looks decent as identification has to be done quickly. Manually checking each machines will take lot of time. Moreover--- even option A says "CPUs" and not GPUs "Log into each Compute Engine instance and collect disk, CPU, memory, and network usage statistics for analysis."
