The resistance of the human body is:
Correct answer: C. 120 kilo-ohm
- A. 120 ohm
- B. 12 ohm
- C. 120 kilo-ohm
- D. 120 Mega-ohm
Explanation
When it comes to the resistance of the human body, there is no fixed value; it exists over a range. The resistance of the human hand can be as high as 100K ohms when dry, whereas when wet, the body resistance can fall to 300 ohms. Hence, the best possible answer in this scenario is 120K ohms.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
