Answer:
Positioning stage of courtship.
Step-by-step explanation:
As the exercise describes, Marco and Kris are most likely at the positioning stage of courtship as this stage shows them close, facing eachother. Marco holding her hand shows how the involvement increased, creating an atmosphere between them that would make others trying to enter it feel like intruders. So what this stage consists of is the increased involvement, a somewhat apropiation of space between the individuals and the keen attention on eachother.
