Sanitation aims to achieve removing visible dirt. This is why options A, B, and D are incorrect. Option A does not go far enough in eliminating bacteria, while option B is too extreme in killing all microbial life, and option D only mentions effectiveness against specific viruses, which is not the primary goal of sanitation. Visible dirt can encompass bacteria, viruses, and other contaminants, so sanitation focuses on the physical removal of these visible substances to create a cleaner and healthier environment.
