Knott's Berry Farm is part of which amusement park chain?

Knott's Berry Farm is part of the Cedar Fair amusement park chain. Cedar Fair operates a number of parks across North America, and Knott's Berry Farm was one of their original acquisitions, cementing its status within this chain. Cedar Fair is known for managing a variety of attractions, including roller coasters and themed rides, making it a popular destination for thrill-seekers and families alike.

The other choices represent different amusement park chains that do not include Knott's Berry Farm. Six Flags is recognized for its own collection of parks that focus heavily on thrill rides and coasters, Disney Parks features family-friendly attractions centered around Disney franchises, and Universal Studios is renowned for its movie-themed rides and experiences. None of these alternatives have Knott's Berry Farm under their management, which reinforces why Cedar Fair is the correct association.
