Final answer:
The term for a payment that goes against legal or ethical standards in the workplace is called bribery. A bonus, gift, or gratuity have different contexts and are not associated with illegal or unethical actions.
Step-by-step explanation:
A payment in some form (cash or noncash) for an act that runs counter to the legal or ethical culture of the work environment is called bribery. The correct option is b) Bribery. In contrast, a gratuity is often a tip or gift given in appreciation for service, a gift is broadly any item given without expecting something in return, and a bonus is a reward for good performance in the workplace.
When a supervisor offers a work-related reward in exchange for a sexual favor, this behavior is specifically referred to as quid pro quo sexual harassment, which is both illegal and unethical.
