Answer
$(3, 0)$
Work Step by Step
RECALL:
In the point $(x ,y)$:
$x$ = directed distance of the point from the y-axis (positive when the point is to the right of the y-axis, negative when to the left)
$y$ = directed distance of the point from the x-axis (positive when the point is above the x-axis, negative when below)
Point C is:
3 units to the right of the y-axis so $x=3$
0 units above the x-axis so $y=0$
Thus, the coordinates of C are $(3, 0)$.
