Answer:
B. They would want to make sure the company's charter contains a shareholder rights provision.
Step-by-step explanation:
If institutional investors believe that the company's poor performance is because management has not focused on maximizing shareholder wealth, they would probably support an amendment to the company's charter that provides a provision that ensures that management is obliged to maximize shareholder wealth.
Like this, management could not ignore this function because it would be codified in the company's charter. It is analogous to when citizens acquire certain rights that cannot be violated by governments because those rights are protected under a constitution.
