Critical Reasoning

In 1977, in his fifth attempt to race through the Grand Canyon, Barnabas Mosby not only raced through the canyon rim to rim, making the roundtrip for thirty-nine miles instead of the minimal nineteen, but he bested the agility achievement as well, by running through the difficult path in almost a day faster than anyone had yet managed.

[A] but he bested the agility achievement as well, by running through the difficult path in almost a day faster than anyone had yet managed

but also bested the agility achievement, running through the difficult path almost a day faster than anyone had yet managed

[C] but also ran through the difficult path almost a day faster than anyone had yet managed, and besting the achievement for agility

[D] but also besting the achievement for agility by running the difficult path in almost a day faster than anyone had yet managed

[E] but running the difficult path in almost a day faster than anyone had yet managed, he also bested the agility achievement

In this option B is the correct choice. But if we chance and besting to ,besting in the option C, then will it be a better choice?
