To find the proportion of the sample with a household income below $35K, we need to locate the corresponding column in the table. We can see that there are 13,164 women who reported a household income below $35K. To get the proportion, we divide this number by the total sample size: 13,164/33,938 = 0.387 = 38.7%. Therefore, choice A is the correct answer.
