AI Explanation
The correct answer is B) vacuum. Gland sealing steam is used during steam turbine operation to prevent the loss of vacuum. Steam turbines rely on a high-vacuum environment to operate efficiently. The gland sealing steam helps maintain this vacuum by preventing air from being drawn into the turbine casing, which would disrupt the vacuum and reduce the turbine's performance. The other options (A, C, and D) are not the primary purpose of gland sealing steam in a steam turbine system.
