An attorney has a duty of ________ to protect the client and to make certain that the client receives advice and representation that is free of conflicting interests.

A) due care
B) loyalty
C) proximity
D) good faith

An attorney has a duty of loyalty to their client, which includes the obligation to avoid conflicts of interest and ensure that their advice and representation is free from any competing interests. This duty of loyalty is a fundamental principle of legal ethics and is codified in most jurisdictions' rules of professional conduct. While an attorney also has a duty of due care to provide competent representation, this duty does not specifically relate to conflicts of interest. Proximity and good faith are not relevant to an attorney's duty of loyalty or conflict of interest issues.
