The blow dryer attachment that spreads airflow gently over a larger area is called

• A. Diffuser
• B. Concentrater
• C. Nozzle
• D. Tail

Answer: (B)

The thing this question is testing is how blow dryer attachments modify airflow. A diffuser is the attachment that spreads airflow gently over a larger area. It has a wide, rounded surface (often with finger-like prongs) that breaks up the jet of air so heat is distributed more evenly and less intensely. This helps curls or textured hair dry without disturbing the natural pattern and with reduced frizz.

In contrast, a concentrator focuses air into a narrow stream for precise styling, which is the opposite of spreading over a large area. A nozzle is a general term for attachments that direct airflow, but it doesn’t specify spreading wide like a diffuser. “Tail” isn’t a standard term for blow dryer attachments. So the best choice for spreading airflow over a larger area is the diffuser.
