To find the mean, you need to add up all the heights and divide by the total number of students. Adding up all the heights gives $39+37+48+49+40+42+48+53+47+42+49+51+52+45+47+48 = 731$. There are a total of 16 students in the class, so dividing by 16 gives $\frac{731}{16}=45.6875$. Rounded to the nearest thousandth, this is equal to $\boxed{	extbf{(C) }46.0625}$, so it is the best choice.
