Answer:
A) Chris, an immigrant who served honorably in the US Navy during a war
Explanation:
After the attacks on the United States on September 11, 2001, Congress added a provision to the Immigration and Naturalization Act that allows people who are on active duty in the US Armed Forces during wartime, regardless of immigration status, to immediately apply for naturalization as a citizen. Chris, an immigrant who served honorably in the US Navy during a war has the quickest path to citizenship.
