Answer
Brief Explanations:
The original sentence suffers from faulty parallelism and awkward phrasing in the introductory prepositional phrase ("With a fun class and the homework was challenging"). To correct this, the items following the preposition "With" should be parallel noun phrases. Option D provides the most effective revision by using parallel structure ("a fun class" and "challenging homework") and a logical conjunction ("so") to connect the cause to the effect, creating a clear and grammatically correct sentence.
Answer:
D. With a fun class and challenging homework, so the girl became interested and smart; she was able to make it into college.
