Explanation

kubectl create -f <file>.yaml is correct because the -f flag specifies a file, and create is an imperative command that instantiates resources defined in that YAML manifest. Option A (kubectl run) is used to run a single container image directly, not to apply a YAML file. Option B (kubectl get pod) is a read operation that lists existing Pods - it creates nothing. Option C (kubectl apply) is close and also accepts -f, but without the flag it is incomplete and would error; more importantly, apply is the declarative approach used for updates and reconciliation, whereas create is the classic imperative way to instantiate a resource for the first time.

Memory tip: Think "Create needs a File" - kubectl create -f. The -f flag is your bridge from a YAML file to a live Pod.
