Final answer:
The category involving interpersonal skills and listening is Doing (practice/skills), as these skills include effective communication and the active application of listening abilities, which are enhanced through practice and participation in social interactions.
Step-by-step explanation:
The category that involves interpersonal skills and listening is C) Doing (practice/skills). Interpersonal skills are part of the practical skills that one can develop and include the ability to communicate effectively with others, both verbally and non-verbally. Good listening is a key part of effective communication; it requires concentration, understanding, and also involves paying attention to the emotions behind the words as well as your own emotional responses. This indicates a clear association with practice and the application of skills rather than just knowledge or attitude. By participating actively in discussions and concentrating on listening effectively, individuals are engaging in the application and development of these crucial communication skills.
The ability to make quick decisions, the importance of valuing human connection, and communicating one-on-one represent the practical elements of social interaction and hence fall under the 'Doing' category. Likewise, reducing frustration and anxiety are outcomes of effective interpersonal communication and skilled listening, both of which are more related to skills practice than mere knowledge or innate being.
