Carl Vinson was extremely supportive of the US Navy in their roll of defense, however, though this is the case he never favored the financial gain of under US military branches to aggregate the Naval funds at the time. So the first answer, answer A, if false. Though Carl Vinson was pro Navy, this didn't mean that the Navy could start retiring it men, the number stayed roughly the same, because of course we had people actually retiring or enlisting. This makes option B false. Other nations were always a threat, maybe no apparent to the US but seeing how the United States reacts to situations, this is a gross understatement. Option C is false. His efforts DID in fact help naval expansion needed in order to defend Pearl Harbor during attack. Option D is correct.
My guess would be the first one
The U.S. acquire Louisiana from france
