The answer you selected results in what is called a "Comma Splice": a comma is used incorrectly to separate two sentences.
One of the choices should have offered the solution with a semi-colon after company, and then a comma after however.
Note that however cannot fill the role of a coordinating conjunction, and cannot replace a period.
After college Susan King founded a publishing company; however, she eventually reduced her role in the firm to pursue her interests in storytelling and art by creating her own books.
That would be correct usage.
