The correct answer is option B. ESB.
The ESB is the technique referred to as electric stimulation of the brain. The electric stimulation of the brain is used for the inhibition or the activation of the brain. This technique is used to treat the conditions, such as Parkinson's disease. In the ESB technique, a weak electric current is applied to the brain, which help in the stimulation of the brain activity (either activation or deactivation).

B) Balanced forces must be acting upon the cart.
C) An unbalanced force applied to the cart pushing or pulling it forward.
D) The unbalanced force acting upon it must be smaller than that of friction.
An unbalanced force applied to the cart pushing or pulling it forward, must occur to a shopping cart at rest in order to make it roll forward, hence option C is correct.
The downward-moving gravitational force will be at work. A force called the normal force will react to the gravitational force in accordance with Newton's third law. And formal force will exert upward pressure.
The magnitude of these two forces is the same. Due to their mutual cancellation, the net force acting on the cart in the vertical direction will be zero.
They may result from factors like magnetism, gravity, or anything else that could speed up a mass. A force in physics is any effect that, if left unchecked, will alter an object's motion.
Therefore, option C is correct.
