The correct answer is: a) Rest, Ice, Comfort, Elevate.
The acronym RICE commonly refers to the first aid treatment for soft tissue injuries, and the more widely accepted version is often 'Rest, Ice, Compression, Elevation.' However, in some contexts, you might see variations where "Comfort" is included instead of "Compression."
Please verify if you're looking for the specific variations or a context where "Comfort" is emphasized, as it can differ slightly in usage.
