Answer to Question 1

ANS: B
Although all body tissues and organs are susceptible to electrical shock, the heart is the most vulnerable because it is governed by electricity.

Answer to Question 2

ANS: D
Grounding provides a path of least resistance that allows current to bypass the body in the event of a short circuit. Ground fault circuit interrupters are circuit breakers that will trip when there is even a small difference between current flowing out through the device and current returning through the device. Underwriters Laboratories certifies devices that are plugged into current sources.
