Answer:
Option (3)
Explanation:
The elasticity property of rock describes how a rock that is subjected to stress undergoes bending and again comes back to its original position. In nature, most of the rocks are non-elastic as they undergo deformation due to the stress acting on them. So the rocks are not always perfectly elastic.
According to Hooke's law, in case of a comparatively small deformations of an object, the displacement that occurs on the rocks or the deformation size that occurs is directly proportional to the amount of load that undergoes deformation.
Hence, the correct answer is option (3).

The fossil range can simply be defined as the time period in which an organism has existed, thus left fossil traces of its existence. The fossil range can be very short, medium, or long, thus usually there are limitations before certain type of organism evolves into another species, thus eliminating the ancestral organism from the fossil records. On the other hand, there are organisms that have incredibly big fossil ranges of several hundred million years, and since they emerged, they have remained almost unchanged. Those kind of fossil ranges are very rare though, and they don't represent the general picture. Most of the fossil ranges are between several thousand years and several million years, as that is usually how much a species exists, ending its reign, be it because of competition, changes in the environment, or big natural disaster.
