Answer:
C. An internship.
Step-by-step explanation:
An internship is a temporary position in a company where a person works for the experience and understanding of the company. The person working temporary is called an intern and trains in the company about how corporates work.
An internship may or may not be a paid position but it is not a permanent job.

This job position allows one to gain knowledge about the company and also acquire experience in the workplace.
Thus, the correct answer is option C.
