B Correct answer
Explanation

Airborne droplet nuclei develop when the fluid of pathogenic droplets (1 to 5 m in size) evaporates. They are so small and light, and they may remain suspended in the air for several hours. Thus, they may also infect persons entering a room which has been left by a patient long ago.
