Creating Cubic Bezier Splines

Decide which spline method is depicted in each of the following diagrams. The crosses represent the supplied spline control points, and the dots are calculated control points for individual cubic Bezier curves that make up the spline. Questions are graded are soon as an answer is selected.
Method 1

What type of spline curve does the above diagram illustrate?
a C0 cubic spline with 3 segments
 a C1 cubic spline with 3 segments
 a G1 cubic spline with 3 segments
a C2 cubic spline with 3 segments
Method 2

What type of spline curve does the above diagram illustrate?
a C0 cubic spline with 2 segments
 a C1 cubic spline with 2 segments
 a G1 cubic spline with 2 segments
 a C2 cubic spline with 2 segments
Method 3

What type of spline curve does the above diagram illustrate?
a C0 cubic spline with 2 segments
 a C1 cubic spline with 2 segments
 a G1 cubic spline with 2 segments
 a C2 cubic spline with 2 segments
Method 4

What type of spline curve does the above diagram illustrate?
a C0 cubic spline with 3 segments
 a C1 cubic spline with 3 segments
 a G1 cubic spline with 3 segments
 a C2 cubic spline with 3 segments
