Final answer:
The correct answer for establishing an effective relationship is that people cannot be selfish and possessive because this goes against natural cooperative behavior and moral standards necessary for societal functioning.
Step-by-step explanation:
To establish an effective relationship with each other, people cannot be selfish and possessive. According to empirical evidence, while humans do have innate selfish tendencies, such as seeking food when hungry or rest when tired, excessive self-focus does not encourage the formation of friendships or trust. Instead, successful social interactions require a moral foundation that includes cooperation and compassion, as excessive egoism leads to being avoided by others.
Living in a world where we face scarcity, we cannot have everything we want—this includes time, money, possessions, and experiences. When looking at the context provided, it can be inferred that being selfish and possessive is not advantageous for building positive relationships, as it goes against the natural cooperative behavior and the moral standards needed for a functioning society.
Therefore, the correct option in the final answer is (ii) cannot be selfish and possessive.
