B. Not moving, is the correct answer.

A is not correct because constant speed on a distance vs. time graph would vertically point to the right. C is not correct because acceleration on a distance vs. time graph would curve upwards. D is not correct because B applies to the graph.

Hope this helps :)

Answer choice A(57%)

Step-by-step explanation:

The margin of error is 7%. This means the 63% could either 7% too high or 7% too low. Answer choice A is the only answer choice that is within the range of percents that it could possibly be(between 56% and 70%). Answer choice B is 10% off, 3% out of the range. Answer choice C is 25% off, 18% out of the range. Answer choice D is 32% off, 24% out of the range. Hope this helps. :)
