Frictional force always acts opposite to the direction of motion or the impending motion of an object, parallel to the surface in contact.
Frictional force always acts in the opposite direction to the relative motion between two surfaces in contact. If there is no relative motion, the frictional force resists the impending motion between the surfaces.
The direction of frictional force between two surfaces is always opposite to the direction of motion. Friction opposes the relative motion or attempts to prevent the sliding of two surfaces past each other. If an object is moving to the right, the frictional force will act to the left.
Frictional force and tension in a string always do negative work because they act opposite to the direction of displacement of the object on which they act. This results in a loss of mechanical energy.
We're forced to go out on a limb here and propose an answer without benefit ofthe "following" list of choices, since, apparently, the question was automaticallytruncated and the choices were lost. It's a shame you went to all that trouble tocopy the choices along with the question, only to see them deleted by some nasty 'bot'.Since the object accelerates in the direction of the applied force, the net force on it ...equal to the vector sum of the applied force and the friction force ... must point inthe direction of the applied force, and so the frictional force must be less than theapplied force.
The direction of friction on a rotating object in a clockwise direction depends on the point of contact. Friction opposes the relative motion between the object and the surface it is in contact with, so the direction of friction will act in the direction opposite to the slipping or sliding motion at that contact point.

Frictional force must always act in opposite directions
The direction of frictional force between two surfaces is always opposite to the direction of motion. Friction opposes the relative motion or attempts to prevent the sliding of two surfaces past each other. If an object is moving to the right, the frictional force will act to the left.

Centripetal Force, it always points to the center of the circle.
Oppose & Prevent
Friction is caused by the interaction of two surfaces in contact. The frictional force opposes the motion of an object or resists the force applied on it. Frictional force is dependent on the nature of the surfaces and the normal force pressing them together.
An indirect force is a force that results from another force being applied in a different direction or manner. It does not act on an object directly but influences it through another force or intermediary. An example is a frictional force that opposes the motion of an object being pushed.
Friction will always act in the direction opposite of the relativistic motion of two objects. If object A is moving to the right on object B, then object A will experience the friction to the left. However, object B will be moving to the left on object A and will therefore experience the friction acting towards the right.
If friction were to act in the same direction as the motion, it would oppose the motion by providing a resistive force. This would result in the object slowing down or coming to a stop more quickly. The kinetic energy of the object would be converted into heat due to the increased frictional force.
