The correct answer is: All of the above

Lightweight joint compound has several advantages that make it a preferred choice for many drywall finishing tasks. One significant benefit is its faster drying time compared to traditional joint compounds. This characteristic allows for quicker application and can expedite the overall finishing process, enabling professionals to move on to additional work sooner. In addition to drying more quickly, lightweight joint compound also generates less dust during application. This is particularly beneficial in maintaining a cleaner workspace and reducing the amount of airborne particulate matter, which can be a concern for both health and cleanliness. Less dust also means easier cleanup and less contamination of surrounding areas. Furthermore, lightweight joint compound is easier to sand once it has dried. This feature simplifies the finishing process, as smooth joints and surfaces are crucial for a professional-looking result. Being easier to sand allows for less resistance and smoother surfaces, making it easier to achieve the desired finish. Altogether, these advantages—faster drying time, reduced dust during application, and easier sanding—underscore the effectiveness of lightweight joint compound for drywall finishing tasks, making the selection of "All of the above" a fitting choice in acknowledging its comprehensive benefits.
