I think the answer is either C or D
Australia is an island country, and besides the big main island and Tasmania, it has around 12,000 islands plus on its territory. Since it doesn't have any land borders, its border line is actually the sum of all coastlines of all islands in its territory, and that accounts for 70,000 km.
New South Wales is the biggest state in the country, and it is roughly around 10% of the total territory of Australia. Its border is 4,635 km, so that means it has 6.62% of the total border line of Australia.
