Solution

The correct option is A 1/10th sec
The human nervous system is highly developed. The external stimulus leads to generation of impulse. This impulse is conducted through sensory neurons and the response is given by the effector organ on receiving the answer given by the brain. The time taken by the brain and the nervous system to give the response is considered as in fraction of a second. So, the correct answer is option B.
