Static electricity refers to a temporary imbalance of charge on an object's surface. This means that there is a build-up of either negative or positive charge on the surface of an object, which can cause the object to attract or repel other objects. Option A, the flow of electrons in a circuit, is incorrect because static electricity does not involve the flow of electrons; it is a stationary charge. Option B, a consistent flow of electrical current, is also incorrect because as mentioned before, static electricity does not involve the flow of electrons. Option D, the electrical potential energy in an object, is incorrect because static electricity refers to the imbalance of charge, not the potential energy. Therefore, the best answer to describe static electricity is option C.
