Answer: (D)

Verified step by step guidance

1. Step 1: Understand the mode of transmission for each disease listed. Lyme disease is transmitted by tick bites, so it is not spread through sharing water bottles.
2. Step 2: Recognize that tuberculosis is primarily spread through airborne droplets when an infected person coughs or sneezes, not typically through sharing water bottles.
3. Step 3: Know that malaria is transmitted by the bite of infected Anopheles mosquitoes, so it is not spread by sharing water bottles.
4. Step 4: Identify that Streptococcal pharyngitis (strep throat) is caused by bacteria that can be spread through respiratory droplets and saliva, making it possible to transmit by sharing water bottles.
5. Step 5: Conclude that avoiding sharing water bottles can help prevent diseases like strep throat, which are spread through saliva and close contact.
