The Greek base that means "to burn" is "Cau(s)-".
To determine this, we can break down the options provided and look for their Greek origins:
1. "Cla-" does not have a direct connection to the meaning of burning in Greek.
2. "Path-" comes from the Greek word "pathos," which means suffering or feeling, but does not relate to burning.
3. "Sat-" doesn't have a direct connection to burning in Greek.
Therefore, the correct option is "Cau(s)-", which comes from the Greek word "kaio" or "kaiein" (καίω), meaning "to burn."
