To configure a rewrite policy to change the version of HTTP from HTTP 1.1 to HTTP 1.0 in every request, the correct command syntax should use the HTTP request context. Thus, the correct answer is: A. The command should be: add rewrite action RW_ACT replace http.req.version "HTTP/1.0" add rewrite policy RW_POL true RW_ACT. This ensures that the HTTP version in the request is replaced with HTTP 1.0 for all incoming requests.
