Size is relative term because it tells the person viewing or painting it how much time it took and other things they did to create it.
The so-called Flemish Primitives were the first to popularize the use of oil paint. Their art has its origins in the miniature painting of the late Gothic period. Chief among them were Jan van Eyck, Hans Memling, Hugo van der Goes, Robert Campin and Rogier van der Weyden.
A compound meter is when beats are divided into three notes so I think the best option would be C. 6/8
