B Correct answer
Explanation

Niagara Falls has never completely frozen solid and stopped flowing. During extremely cold winters (including 1932), ice formations and ice bridges have created the appearance of freezing, and water flow has been partially obstructed by ice jams, but water continues to flow beneath. The falls simply cannot freeze completely due to the enormous water volume.
