To determine the filtration process that uses beads to remove volatile organic compounds (VOCs) and other organic material, let's analyze the provided options:

1. Activated Carbon: This is a material made from carbon that has been processed to have small, low-volume pores. These pores increase the surface area available for adsorption or chemical reactions. Activated carbon is highly effective for removing VOCs and other organic materials from water and air due to its adsorptive properties.

2. Sand Filter: This is typically used in water filtration systems to remove suspended solids from water. While sand filters can effectively remove larger particles and some pathogens, they are not specifically effective for VOCs or organic compounds compared to activated carbon.

3. Membrane Filter: This type of filtration employs a semipermeable membrane to remove particles from liquids and gases. Membrane filters can remove pathogens and particulate matter effectively, but they are not typically aimed at the adsorption of VOCs.

Conclusion

Based on this analysis, the most appropriate choice for a filtration process that uses beads to remove VOCs and other organic material is Activated Carbon.
