  2. a conductor carrying a current greater than 1 microamp enters the body through the skin.
  3. a conductor carrying a current greater than 100 microamps enters the body through the skin.

C: Microshock refers to electrocution by a current above about 100 μA if delivered by a conductor that has penetrated the skin. Currents less than this are probably not fatal. If the current greater than 100 mA is applied to the exterior of the skin, it is called microshock. Choice D is referring to external defi brillation.
