Answer:
Correct Answer: C
Solution:
Human body, though has a large resistance of the order, of $ K\Omega $ (say $ 10k\Omega $ ), is very sensitive to minute currents even as low as a few mA. Electrons excite and disrupt the nervous system of the body and hence one fails to control the activity of the body.
