Final answer:
b) Long-distance relationship communication
Shawna and Jason's regular video chats during his deployment exemplify long-distance relationship communication, providing essential family support.
Step-by-step explanation:
The example given of Shawna's husband, Jason, who is deployed to Afghanistan and video chats with Shawna and their children every Sunday evening, is an example of long-distance relationship communication.
Military families like Shawna's often face long periods of separation due to deployments, and maintaining communication is crucial for family cohesion and emotional support.
This scheduled and regular communication through video chats helps to manage the stress and detachment that Jason might experience due to his deployment and supports the family's adjustment process during his absence.
