Explanation:

The original sentence "Heavy, black clouds rushing in from the horizon" is a fragment as it lacks a main verb. The first option "Heavy, black clouds rushing in from the horizon mean a storm is coming" adds a main verb "mean" and makes it a complete sentence. The second option "Heavy, black clouds rushing in from the horizon when it's about to rain" is still a fragment (dependent clause). The third option "Heavy, black clouds rushing in from the horizon. get under cover." has a sentence - fragment (first part) and a comma - splice (if we consider it as two parts). The fourth option "Heavy, black clouds rushing in from the horizon. It's about to rain" is two separate sentences but the first one is a fragment.

Answer:

Heavy, black clouds rushing in from the horizon mean a storm is coming.
