Explanation

In kubectl, the -n flag stands for namespace, which is a Kubernetes mechanism for isolating groups of resources within a cluster - so kubectl -n prelude get pods lists pods specifically within the prelude namespace. Nginx (B) is a web server/proxy and has no relation to this flag; Node (C) refers to a cluster worker machine, targeted instead with --field-selector spec.nodeName=... or node-specific subcommands; New Deployment (D) is not a kubectl concept at all. A reliable memory trick: think "-n = named space" - you're naming which space (namespace) to look in, just like specifying a folder before listing its files.
