Bgrounding the plastic case through a short
Cburning out the motor from an overload
Doverloading the motor from a short
AI Explanation
The correct answer is A) electric shock if the tool is shorted. All portable electric tools should have a ground connection to prevent electric shock in the event of an internal short circuit within the tool. The ground connection provides a low-resistance path to divert any fault current away from the user, reducing the risk of electric shock. The other answer choices are incorrect because they do not directly address the purpose of the ground connection, which is to prevent electric shock.
