ABy applying NetworkPolicies that specify namespace selectors

BBy assigning different IP ranges to each namespace

CBy disabling the cluster network plugin

DBy using host networking for Pods

Step-by-Step Solution

Solution:

Step 1: Understand namespace traffic control
NetworkPolicies can restrict traffic by selecting Pods and namespaces using selectors.
Step 2: Evaluate other options
Assigning IP ranges per namespace is not standard; disabling network plugin breaks networking; host networking bypasses Pod isolation.
Final Answer:
By applying NetworkPolicies that specify namespace selectors -> Option A
Quick Check:
NetworkPolicies + namespace selectors = traffic restriction [OK]
