The correct answer is C. Ron should send a prospecting letter to see if there are any unadvertised openings.
Step-by-step explanation:
If you are interested in working at a specific company, one of the first steps is to check whether there are any openings or job offers, this can be done by checking the online page, contacting the company or similar. However, in some cases, you might not find any opening listed and because this does not necessarily mean there is not any job offers it is always a good idea to send a prospecting letter to show your interest in getting a job in the company. In this way, the employer can know you and consider you for any current or future job offer. This means, in the case of Rone he "should send a prospecting letter to see if there are any unadvertised openings".
