Answer 1

Among the responses listed, **frequent handwashing** is the most effective strategy at reducing or preventing illness. Regular handwashing is a key practice in preventing the spread of infectious diseases, including colds, flu, and gastrointestinal infections. The other strategies may have their benefits but are not as universally effective in preventing illness as good hand hygiene.
