Explanation:
Here we replace the comma(,) with a semicolon(;) and put a conjunction after it(and). The run-on sentence in the original sentence is that it's missing a conjunction that fits together the 2 independent clauses.
We fix this with the semicolon replacing the comma and an "and" after it.

Explanation:
from what i think, i think its best if you use that choice. in this sentence chosen you have a comma to help give a stop in a sentence and right after the comma you have the word "and". i dont know if this make sense but i hope it does :)
