The government will give the same amount of available social security number to each state. So the available social security number pool will be divided by the total number of states. There are a total of 50 states in the USA. If the number pool is 5 x 10^9, then each state going to have:
5 x 10^9 /50= 0.1 * 10^9 = 1*10^8
The answer will be D since 1 x 10^8 and 100,000,000 is the same number
