The sampling ratio is the ratio between the sample size and the population size. In this case, the sample size is 350 and the population size is 35,000. So the sampling ratio is:
Sampling Ratio = Sample Size / Population Size
Sampling Ratio = 350 / 35,000
Sampling Ratio = 0.01
Therefore, the best choice is B, with a sampling ratio of 0.01.
