Answer

D) Flow Separation Explanation 1. Identify the characteristic sound Rustling sounds are typically associated with turbulent airflow or disturbances in fluid flow. 2. Match options to characteristics Shedding vortices, Helmholtz resonance, cavity resonance, and flow separation all involve fluid dynamics. However, **flow separation** often results in a rustling sound due to turbulence created when the flow detaches from a surface.
