Answer

Brief Explanations:

The third option uses appropriate conjunctions ("and", "or", "however") to connect ideas smoothly. "Running is great exercise, and it is inexpensive" connects the two positive aspects of running. "You can run on a treadmill, or you can run outdoors" shows an alternative. "You should not run on icy roads, however" provides a contrast. The first option has an incorrect use of "or" (running being great exercise and inexpensive are not alternatives). The second option has an illogical use of "yet" (running being inexpensive has no contrast with running on a treadmill).

Answer:

Third option: Running is great exercise, and it is inexpensive. You can run on a treadmill, or you can run outdoors. You should not run on icy roads, however.
