On a nautical chart, which symbol identifies prominent landmarks such as towers and flagpoles?

Explanation:
Tall, easily seen man-made features are marked on nautical charts with a simple symbol to stand out from the surrounding detail. The circle denotes prominent landmarks such as towers and flagpoles, making them easy to spot from the water and to use for position fixes. Other shapes aren’t used to identify these landmarks—diamonds, squares, and triangles represent different kinds of chart information, so they wouldn’t correctly indicate a tower or flagpole.
