The declaration of independence became a. a law of the land b. a model for many other colonies c. the u. s. constitution

The Declaration of Independence became a "model for many other colonies." Colonies are areas of land that are owned by another country. When the US declared independence from Britain, many other colonies followed suit. It wasn't a law of the land, and the U.S. Consitution came later.

"B" is the best answer.

I hope this helps!
