Moderate activities are like going to the park and walking your dog or going to the mall. Vigorous activities such as sports, paintball and theme parks.
Immunisation, public health promotion to raise awareness and knowledge (e.g. Ads, at the provider-patient level)
Targeting and improving infrastructure for public welfare! e.g. Sewerage services for clean water
Screening for early diagnosis and treatment
Quarantining if required..
Though the word "potential" is throwing me off a bit here, are they asking you for novel strategies instead of solid ones?
I would say C because the other ones seem like they would help make it get that syndrome HOPE THIS HELPS :)
