Answer:
C. one solution 
Step-by-step explanation:
The number of solutions can be found from the number of intersection points. 
There are 2 lines, a parabola (curve) and a horizontal line that is parallel to the x axis. 
We see that there is 1 point of intersection between the 2 lines, at (2,1)-right 2 and up 1. Therefore, this non linear system has 1 solution. 
C. one solution is the correct answer.
