Explanation

Correct Answer: C - Yes, by completing Sanderson's suitability analysis based on limited information

Analysis:

1. Standard III(C) - Suitability: Under this standard, members and candidates must:

   • Make suitable investment recommendations based on a client's financial situation, risk tolerance, and investment objectives
   • Make reasonable inquiry into a client's financial situation, investment experience, and investment objectives

2. Key Violation:

   • Atkins completed the suitability analysis based on limited information because Sanderson refused to fully disclose his holdings
   • This violates the requirement to make reasonable inquiry into the client's complete financial situation
   • Without full disclosure of existing holdings, Atkins cannot properly assess the overall portfolio risk, diversification, and suitability of new recommendations

3. What is NOT a violation:

   • Option B is incorrect because investment professionals are not responsible for preventing losses that result from unexpected market movements
   • The large loss was due to "unexpected changes in market sentiment" - this is market risk that cannot be controlled
   • The fact that Atkins did "careful research" shows due diligence in the investment selection process

4. Professional Responsibility:

   • When a client refuses to provide necessary information, the professional should:
     • Document the refusal
     • Consider whether they can provide suitable recommendations without complete information
     • Potentially decline to take on the client if they cannot fulfill their professional obligations

Conclusion: Atkins violated Standard III(C) by proceeding with suitability analysis and recommendations without complete client information.
