China's population is 1.45 x 10^9 and India's population is 1.4 x 10^9.
To find the difference between the two populations, you subtract the smaller population from the larger population.
1.45 x 10^9 - 1.4 x 10^9 = 0.05 x 10^9
Simplifying, 0.05 x 10^9 = 5 x 10^7
Therefore, the answer is 5 x 10^7, or option 1.
