Final answer:
The NYPIUA has the right of authority when an agent submits an insurance application to them; they are responsible for reviewing the application to decide on eligibility and coverage.
Step-by-step explanation:
When an agent submits an application for property insurance to the New York Property Insurance Underwriting Association (NYPIUA), the entity that has the right of authority is d) NYPIUA. After the submission of the application, NYPIUA reviews it to determine eligibility and coverage availability. The general agent, the company appointing the agent, and the applicant do not have the 'right of authority' in this scenario, as that right specifically pertains to the underwriting decisions made by NYPIUA itself.
