How is the data represented on a scatterplot that depicts an exponential model?

The choices can be found elsewhere and as follows:

a. points on a line 
b. random points 
c. points on a horizontal line 
d. points on a curvy line

I believe the correct answer is option D. The data represented on a scatterplot that depicts an exponential model would be points on a curvy line. Hope this answers the question. Have a nice day.
