Answer: Im not sure but i think its A
Explanation: i did reasarch on the web and a lot of sources said that they wanted to make a big assult on japanese wanted to assult directly. and by looking at the made they can also use the ocral refs but they have 2 locations that can attack derictly if they wish to do so. so i think its a or B because capturing surrunding islands would take too long pluse they can be renforced with the main and so to kill 2 birds with one shot i think they would attack directly. plz let me know if i was right or wring
