Answer:
The option that best characterizes the type of relationship they seem to have is letter C) competitive symmetrical.
Explanation:
In symmetrical relationships, both people react in the same manner to power. They either want to avoid it or to have/control it. In a competitive symmetrical relationship, both people compete for control; they both want to dominate the relationship. That is precisely the case with Liza and Charles. They wish to impose their different opinions, which always leads them to argue about every decision that has to be made.
