The force that keeps a rope taut is called...

Explanation:
Tension is the pulling force transmitted along the length of a rope when it is pulled tight at its ends. This internal force stretches the rope just enough to keep it straight and taut, so every part of the rope pulls on the adjacent parts and on the objects it connects. Normal force, friction, and gravitational force are different kinds of forces: normal force acts perpendicular to a surface, friction resists sliding along a surface, and gravity pulls objects toward the center of the Earth. None of these describe the force that keeps a rope stretched along its length, which is tension.
