Question:

Which conclusion does the data most directly support?

A The heart rate of the mice increases as the temperature in a room increases.
Explaination

If you picked answer (D), you noticed that the data table shows that as the temperature in the room increases, the heart rate of the mice increases by 100 beats per minute for every 5 degrees Celsius. Answer (A) is incorrect because movement of the mice is not found in the graph. Answer (B) is incorrect because the graph does not show if the mice are able to survive below 5 degrees Celsius or not. Answer (C) is not correct because the data is not exponential but rather linear.
