Answer:
c. a proper purpose.
Explanation:
Proper purpose is an action taken by a shareholder or member of a corporation that is reasonable related to his position or rights.
With the proper purpose rule there is a constraint on a director's autonomy within an organisation and it provides checks to excesses by the management team.
Erin demands the right to inspect corporate records to determine whether management has engaged in self-dealing that impacts the company.
As a shareholder she is enforcing proper right and the court will uphold this.
