Given:
A geometric figure.
To find:
The point of tangency in the given figure.
Solution:
We know that, the point of tangency is a point where the tangent line touches the curve.
From the given figure it is clear that, two lines touch the circle at R and Z.
These two lines are tangent and they touch the curve at points R and Z. So, R and Z are point of tangency.
Therefore, the correct option is C.
