Selected Answer: C

C is correct: For blue/green deployment, Before install is one of several hooks that come before <the replacement instances> start to handle request traffic. A and B: these hooks come after the replacement instances start to handle request traffic. They are hooks from the original instance, which are two of 3 last steps. D: There is no such hook in blue/green deployment
