The best answer is D
A freely suspended magnet will always point in the North - South direction in the absence of any other magnet. This suggests that the earth itself behaves as a magnet which causes a freely suspended magnet (or magnetic needle ) to point always in a particular direction namely North and South.
The south pole of the earth's magnet is in the geographic north because it attracts the north pole of the suspended magnet and vice versa. However it is important to note that the position of earth's magnetic poles are not well defined because they are spread over an area.
Common examples of this would be if you place your hand in extremely warm or cold water, and an immediate response of pulling out of the water or any fluid, is an example of this extreme response, other responses are what is done in everyday, like being thirsty or hungry etc.
These behaviours are shared by all organisms even the most simple ones.

Explanation:
In order to determine this, we will require some pieces of meat, preferably taken from the same animal and from the same area and of similar size. After the pieces of meat are obtained, they are sealed in a container with equal quantities of meat tenderizer. Then, keep the containers in different temperatures.
After fixed time intervals, say 3 hours, record the appearance and texture of the meat. Repeat this until readings for 5-6 time intervals have been obtained.
