The correct answer is A. The Navigation Acts controlled all colonial trade.

Explanation:

The Navigation Act was a law passed by England on 9 October 1651, which allowed goods to be brought into England and its colonies from outside Europe only by English ships. The ban also applied to some European products, but ships were generally allowed to import goods from their own country into England.  

The ban lasted for two hundred years until 1849, although it was amended and supplemented several times. For example, the Navigation Act of 1663 required that American settlements be allowed to ship goods only from English ports by English ships.

it affected it because the kingdoms (with trade) slowly got richer and richer.
