  option A is correct, but do not use it in real deployments, it is a bad practice. I am wondering why they didn't mention Cluster IP and exposing it via an ingress or at least a service of type loadbalancer

  In Kubernetes, a Service of type NodePort is a way to expose your applications to external traffic. It's one of the several types of Services available in Kubernetes to control how external sources can access services running within the cluster. Here's what a NodePort service entails: Exposing Services Outside the Cluster: A NodePort service makes your application accessible from outside the Kubernetes cluster by opening a specific port (the NodePort) on all the nodes (VMs) in your cluster. This port is randomly selected from a defined range (default: 30000-32767) unless you specify a particular port.

  When a NodePort service is created, each node in the cluster allocates the specified NodePort. External traffic can access the service by hitting any node's IP address at the NodePort, regardless of whether that node is actually running a pod for the service. Kubernetes internally routes that traffic to the appropriate pods, even if they are running on different nodes.
