C. Start a new sentence
Starting a new sentence when encountering a comma splice will put more emphasis in both independent clauses and will create a larger break. When you have a long run-on sentence (as in example 5), then you will most likely want a new sentence start. This gives the reader a break when reading.
5. The bat cracked as the ball collided, the sound echoing through the field, the crowd roared and stood on their toes as the ball arced and landed neatly in the outfielder’s mitt.

I started a new sentence after “field” as this sentence is a run-on. It is long: two independent clauses with one including a participle phrase. Making this into two separate sentences breaks the reading up for the reading and allows for better comprehension and flow of the story.
10. Writing fanfiction is stress-relieving, it is a world of its own.

Splitting this with a new sentence start allows for the two sentences to stand apart. They are two descriptions of the same thing, but they are both equally as important.
You are also going to want to use this method to resolve a comma splice when in dialogue, as you want to avoid semi-colons in dialogue in general. A new sentence start or an Em dash (next week) will resolve the comma splice in dialogue without giving into the issues that can be caused by semi-colons.
