Given a text T, and several options, according to the question posed in the text T to choose the most appropriate option from the options as the answer, please directly output the most appropriate option, do not need to output the explanation.

Espey Jones is examining the relation between the net profit margin (NPM) of companies, in percent, and their fixed asset turnover (FATO). He collected a sample of 35 companies for the most recent fiscal year and fit several different functional forms, settling on the following model:lnNPMi = b0+ b1FATOi.The results of this estimation are provided in Exhibit 1.

| Residual | 32 | 2.2152 | 0.0692 |
| Total | 33 | 105.1303 |



At a 0.01 level of significance, Jones should conclude that:
Option A:the mean net profit margin is 0.5987%.
Option B:the variation of the fixed asset turnover explains the variation of the natural log of the net profit margin.
Option C:a change in the fixed asset turnover from 3 to 4 times is likely to result in a change in the net profit margin of 0.5987%.

Answer: B
