• A. Beaker
• B. Ring Stand
• C. Ring clamps
• D. Condenser

Answer: (B)

Holding glassware securely during an experiment is achieved with a ring stand. A ring stand provides a stable base and an upright rod to which clamps and rings can attach, letting you suspend beakers, flasks, or other glassware exactly where you need them. The clamps—ring clamps, versatile clamps, or 3-prong clamps—secure the glassware to that rod, allowing you to adjust height and orientation while keeping hot or reactive items safely positioned above the bench. A beaker is just a container for holding liquids and doesn’t offer a mounting point. A condenser is equipment used to cool vapors in distillation and isn’t meant to support glassware by itself. Clamps need a stand to function as mounting points, so the ring stand is the accessory designed to hold and support glassware with clamps.
