There are four ways to correct a run-on sentence.
1) Join the two clauses with a comma and a coordinating conjunction. This is letter B.
2) Break the run-on sentence into two separate sentences. It should be:
The Belt of Orion has three bright stars in a row. It is visible in the Northern Hemisphere.
3) Join the clauses with a semi-colon and a conjunctive adverb followed by a comma.
The Belt of Orion has three bright stars in a row; consequently, it is visible in the Northern Hemisphere.
4) Join the clauses with a semi-colon.
The Belt of Orion has three bright stars in a row; it is visible in the Northern Hemisphere.
