Answer: The correct answer is:
- A. Writing a state constitution to protect the rights of its citizens
The first step in the process of Washington becoming a state was the writing of a state constitution. In 1889, a constitutional convention was held in Olympia, Washington, where a constitution was drafted for the new state. This constitution included provisions to protect the rights of citizens, such as the right to vote, freedom of speech, and the right to bear arms.
After the state constitution was written, it was submitted to the U.S. Congress for approval. Once Congress approved the constitution, Washington was admitted to the Union as the 42nd state on November 11, 1889.
