Choice A rationale:

All types of meningitis cannot be prevented by vaccination. While vaccinations are available for certain types of bacterial and viral meningitis, they do not cover all possible pathogens that can cause the disease.

Choice B rationale:

Meningitis can be prevented through prophylaxis measures, but this statement is not entirely accurate. Prophylaxis may be given to close contacts of individuals with certain types of bacterial meningitis to prevent its spread, but it does not apply to all cases of meningitis.

Choice C rationale:

Infection control measures are effective in preventing meningitis outbreaks. This statement is incorrect as infection control measures are crucial in controlling the spread of infections, but they cannot entirely prevent all cases of meningitis.

Choice D rationale:

Hygiene practices, such as regular handwashing and proper respiratory etiquette, play a significant role in preventing meningitis transmission. By reducing the spread of respiratory and oral pathogens, the risk of meningitis can be lowered. However, it is important to note that not all forms of meningitis are entirely preventable through hygiene practices alone, which is why vaccination remains a critical preventive measure for specific types of meningitis.
