Answer
Brief Explanations:
An independent clause can stand alone as a complete sentence. "While the team made their play, the frenzied crowd cheered them to victory" has the independent clause "the frenzied crowd cheered them to victory" which has a subject (crowd) and a predicate (cheered them to victory) and can be a complete thought. The other options are all dependent - clause starters (because, when, as) which cannot stand alone.
Answer:
While the team made their play, the frenzied crowd cheered them to victory.
