Final answer:
The maximum gift amount cannot be determined from the given options without specific organizational policies or legal guidelines. The reference to students receiving $250 or more appears unrelated to the question of gift-giving limits in a professional setting.
Step-by-step explanation:
The question refers to the maximum amount allowed to be given as a non-monetary gift to a superior or to receive from a subordinate. However, the provided information regarding the expected number of students to receive $250 or more does not directly answer the question concerning gift limits in a workplace or formal setting. To accurately determine the maximum allowable gift amount to a superior or from a subordinate, one would need to refer to the specific policies of the organization, government regulations, or the ethical guidelines that may dictate these limits. These could vary significantly between different institutions or according to local laws.
As such, without additional context or reference to specific guidelines, it is impossible to provide an accurate answer with the choices provided (A. $25, B. $50, C. $75, D. $100). Furthermore, the latter part of the question pertaining to a sample of 200 students receiving $250 or more seems unrelated, and thus the correct choice is D. Cannot be determined.
