The acronym VSV represents which of the following?

Correct Answer: Option C — Variable Stator Vane.

Variable Stator Vanes (VSV) are adjustable airfoils located in the compressor section. By changing their angle, the control system optimizes the airflow and angle of attack across the compressor blades at different engine speeds. This prevents compressor stall and surge, significantly improving engine efficiency and stability during transient operations.
