C gated part of a river that raises or lowers the water level
D waterway dug across land for ships to go through

The correct answer is D) waterway dug across land for ships to go through. To determine the right answer, we need to understand the definition of a canal and then analyze each option.

1) A flat-bottomed boat that carries goods: This option does not describe a canal. It describes a specific type of boat used for transporting goods.

2) Prehistoric period when Earth was covered with ice: This option describes the Ice Age and is not related to a canal.

3) Gated part of a river that raises or lowers the water level: This option describes a lock, a device used in canals to raise or lower water levels. While it is a component of a canal, it does not fully encompass the definition.

4) Waterway dug across land for ships to go through: This option accurately describes a canal. A canal is an artificial waterway constructed by humans to connect rivers, lakes, or seas, allowing ships and boats to navigate through.

By analyzing each option and understanding the definition of a canal, we can determine that option D, "waterway dug across land for ships to go through," is the correct answer.
