Explanation:

• Option A is incorrect because Standard III(A) (Loyalty, Prudence, and Care) suggests that a cost-benefit analysis might reveal that voting all proxies may not always benefit the client. Therefore, voting proxies is not mandatory in every instance.

• Option B is correct. According to Standard III(A), proxies hold economic value for clients, and members must ensure they safeguard and maximize this value. This aligns with the obligation to act in the client's best interest.

• Option C is incorrect. Standard III(A) emphasizes that blindly voting with management on nonroutine governance matters (e.g., changes in company capitalization) without considering the implications may violate the standard. Thus, a policy of always siding with management on such issues is not accurate.

This question tests the application of ethical and professional standards, particularly the Code of Ethics and Standards of Professional Conduct, in scenarios involving professional integrity.
