Which of the following best explains why the engineers used concrete to build this part of the bridge?

• Concrete is low in density so this part of the bridge can float on top of the water.

• Concrete is heavy so this part of the bridge can move back and forth in the wind.

• Concrete is low in density so this part of the bridge can move back and forth in the wind.

• Concrete is high in strength so this part of the bridge can support a large amount of weight.
