Which revision correctly combines these two sentences?

roses have a beautiful scent. the ones in my grandfather's garden especially fragrant^

The answer is C. You may use a semicolon to combine two sentences when the information in both are closely linked. You cannot use a comma as that would make it a run-on. Just simply adding ‘and’ to combine would make it a run-on as well. You cannot use a semicolon with the coordinating conjunction ‘and’ as this is not correct. You would use a comma with ‘and’ to combine the two sentences.
