Option B is the run-on sentence: 'Mike left his job he could not stand his boss.' This fuses two independent clauses with no punctuation or conjunction. Option A is correct (uses 'because' properly). Option C is correct (uses semi-colon properly). Option D is correct (uses 'as' as a subordinating conjunction). Run-ons occur when independent clauses lack proper connection.
