Instrumental communication refers to:

• A. Messages aimed at accomplishing the task at hand
• B. Demonstrating feelings through nonverbal cues
• C. Explicit statements
• D. Vague information

Answer: (A)

Instrumental communication is goal‑oriented and task‑focused. It involves sending messages that are meant to get something done—directions, requests, instructions, or information shared to move a task forward and achieve a specific outcome. In this sense, the purpose is practical and outcome driven.

That makes this option the best fit because it directly captures the idea of using communication to accomplish a task. The other ideas describe different aspects: expressing feelings through nonverbal cues aligns with affective or relational communication, explicit statements can be part of instrumental use but aren’t the defining feature, and vague information fails to advance a task effectively.
