Based on your description of the painting "Regatta on the Grand Canal in Honor of Frederick IV, King of Denmark" by Luca Carlevarijs, it is likely that all the elements and principles mentioned (perspective, movement, and variety) are present in the image. However, symmetrical balance may not be as evident in a dynamic scene like a regatta, which often features asymmetry due to the arrangement of boats and people.
Therefore, the correct answer is symmetrical balance.
