Final answer:
Attractiveness is NOT a corner of the Triad of Trustworthiness. The foundational elements of trustworthiness include honesty, ability, and reliability, not physical appearance or likability.
Step-by-step explanation:
The corner of the Triad of Trustworthiness that is NOT one of its components is c. Attractiveness. This concept is derived from principles of ethical behavior and psychological frameworks suggesting that trustworthiness is founded on aspects such as honesty, ability or competence, and reliability or consistency. Attractiveness does not typically factor into trustworthiness in a professional or educational context, as it is not related to one's ethical actions or credibility.
On a similar thematic note, when discussing characteristics that are not aligned with certain established principles or systems, it might be helpful to know, for example, that coercion to join is not a characteristic of bureaucracies, mercy was not one of Franklin's thirteen virtues, and the highest form of political power is often considered to be legitimacy. Moreover, in the context of food security, transformation is not traditionally listed as one of the four pillars, which are in fact availability, access, utilization, and stability.
