Which statement best describes droplets in this material?

Droplets are the larger respiratory particles produced when someone talks, coughs, or sneezes. Because they are relatively heavy, they don’t stay suspended in the air for long and tend to settle quickly onto surfaces or onto nearby people. They typically travel only a short distance from the source—about 3 feet (roughly one meter)—before gravity pulls them down. That short-range behavior is why protecting yourself with appropriate barriers and keeping others at a close distance reduces transmission risk. The other descriptions describe aerosols, which are small particles that can linger in the air for longer periods, and the idea that droplets cannot transmit infection is incorrect because droplets can carry and transfer pathogens when they reach mucous membranes or contaminated surfaces.
