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, get under cover" has a comma - splice error (two independent clauses joined by just a comma). The second option "Heavy, black clouds rushing in from the horizon. It's about to rain" is two separate sentences but the first is still a fragment. The third option "Heavy, black clouds rushing in from the horizon when it's about to rain" is a dependent - clause - like structure and not a complete sentence. The fourth option "Heavy, black clouds rushing in from the horizon mean a storm is coming" has "mean" as the main verb, making it a complete sentence.

Answer:

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