Final answer:
A fallen tablet should be disposed of in a designated electronic waste bin to prevent environmental pollution and adhere to e-waste disposal guidelines.
Step-by-step explanation:
The proper way to dispose of a tablet that has fallen on the floor in an individual's room is to place it in a designated electronic waste bin. Electronic devices should not be thrown into the regular trash due to the potential environmental hazards they pose. Many tablets and other electronics contain toxic chemicals and precious metals, which can cause serious pollution and health risks if disposed of improperly. It's essential to follow government safety guidelines for e-waste disposal to prevent these materials from contaminating our environment.
