……. force that is transmitted through a string, rope, cable etc. When it is pulled by forces acting from opposite ends.
A. Normal Reaction
B. Tension
C. Gravitation
D. All

Hint:In order to solve this question we will use the definition of force defined by Newton’s Law. According to which Force is defined as rate of change of momentum. Also it could be defined like force is interaction that can change the state of the body i.e. if rest then it causes motion and vice versa.

Complete step by step answer:
Let us consider each option and find the answer. Considering option [A] Normal Force. Normal Force is defined as that force which a plane applies in reaction to the force by which body pushes the plane. It always acts in a direction perpendicular to the plane. It can only act when there is pushing force by body on plane. So from this definition force in string is not normal force

Considering option [B] Tension Force. Tension Force is defined as that pulling force which acts whenever there is pull in the body through rope, cables and extensions. It gets transmitted in rope through atoms or constituting particles. So according to the given question Tension force that is transmitted through a string, rope and cable etc.

Considering option [C] Gravitational Force. Gravitational force is an attractive force which acts between two masses having some distance between them. Its formula is given by
$F = \dfrac{{G{m_1}{m_2}}}{{{r^2}}}$
where, ${m_1}$ is the mass of one body, ${m_2}$ is the mass of another body and $r$ is the distance between them $G$ is the gravitational force constant.

Hence, the correct option is B.

Note:It should be remembered that, both Tension forces and Gravitational force have direction defined by distance between two acting bodies whereas Normal force has just one direction that is perpendicular to the plane on which it is acting. Also it should be remembered that Tension force and Normal Force both are contact force whereas Gravitational Force is non-contact force.
