In the decision-making process, all of the following are examples of taking action except:

A. volunteering at an animal shelter.

B. working part-time after school.

C. applying to college.

D. researching internship opportunities.

The first three options I see are all making-decision process to take action, but the last one is the one that is not like that. Researching is something that is not so close in meaning to what you need. That is why, D is a good option.
