Negative Force

Explanation:

Here we know that man pulls on his dog leash to keep him from running after bicycle

As we know that here tension force is acting on the dog which is applied by the man and due to this force the dog is not moving but this force is just required to keep the dog at rest

So here this force is not doing any work as we know that work done is product of force and displacement

So here this force is equal and opposite the force which is applied by dog to run towards bicycle

So this force can be termed as negative force

So correct answer will be

Negative Force

i think the answer is a, hope this is right, that would be my best guess.
