We can get the number of self-employed men as well as he number of self-employed women at the end of Year X, and compare. Sufficient.
To illustrate:
From the end of Year X to the end of year Y, the number of self-employed men increased by 47 thousand, which was an increase of 1 percent: (The number of self-employed men)*0.01=47,000 --> we can get (The number of self-employed men).
From the end of Year X to the end of year Y, the number of self-employed women increased by 213 thousand, which was an increase of 10 percent: (The number of self-employed women)*0.1=213,000 --> we can get (The number of self-employed women).
(2) At the end of year X, there were 2.57 million more self-employed men than self-employed women. We cannot get the rato from this info. Not sufficient.
Answer: A.
Hope it's clear.

10 % = 213,000/y = female at year X
clearly sufficient.
stmt 2 cleary IS. so A
