When adding curves there are some common options like other Objects.

In Object/Edit Mode, the Add Surface menu, provides six different surface primitives:

NURBS curve primitives.

NURBS Curve

Adds a generic curve of four control points forming an arc.

NURBS Circle

Adds an a closed loop of control point forming a circle. Note, a circle NURBS surface is never filled, unlike its «real» curve counterpart…

NURBS Surface

Adds a generic surface patch consisting of a 4×4 grid plane with the center grid slightly raised.

NURBS Cylinder

Adds an open end cylinder, consisting of an extruded NURBS Circle.

NURBS Sphere

Adds a generic sphere constructed by revolving a grid of control points about an axis.

NURBS Torus

Adds a doughnut-shaped primitive created by rotating a circle around an axis.
