The correct answer is <em>citizens voted to move the capital</em> (option a). Guthrie became the first state capital of Oklahoma in 1907, but in 1910 state voters decided to move the capital to Oklahoma City, a larger city south of Guthrie.
There had been a rivalry between Guthrie and Oklahoma City for the location of the Capital of Oklahoma.In June 11, 1910, a vote was conducted and a majority of the people chose Oklahoma City as the State capital. It was then affirmed as the state capital.
The seal was then moved from Guthrie to Oklahoma City.
