C. Prioritizing
Step-by-step explanation:
Stress managment is something you do to manage or take care of your stress. For example you may want to watch TV because that makes you calm.
Tension reduction is something you do to take away some tension or relax. An example would be taking a nap.
Prioritizing is knowing when an activity is more important than another so you can figure out witch needs to be done first. For example feeding the dog is more important than cleaning your room because the dog needs to be fed, but your room does not need to be cleaned it just makes it look nice.
Time Managment is using your time wisely. This means that you are getting as much done as you can when you have the time.
