Final answer:
An attorney may use tactics that are consistent with professional standards of honesty and fairness during negotiations, adhering to high ethical practices and respecting the legal process (C).
Step-by-step explanation:
Under generally accepted conventions in negotiation, an attorney may use tactics that are consistent with professional standards of honesty and fairness. The legal profession demands adherence to ethical practices; therefore, any form of dishonesty, such as misrepresenting the law or using false statements, is neither tolerated nor ethical. Lawyers are expected to maintain high standards of integrity while representing their clients, respecting both the law and the rights of the opposing party. This includes the right to an attorney and the right to remain silent, among other rights that safeguard the legal process.
Additionally, ethical considerations and professional responsibility guide lawyer conduct during negotiations, as well as in courtroom proceedings, ensuring that the tactics employed do not impair obligation of contracts or abridge the privileges or immunities of citizens.
