Identify the option that has the most appropriate sequence such that a coherent paragraph is formed:
P. Over time, such adaptations lead to significant evolutionary changes with the potential to shape the development of new species.
Q. In natural world, organisms constantly adapt to their environments in response to challenges and opportunities.
R. This process of adaptation is driven by the principle of natural selection, where favourable traits increase an organism's chances of survival and reproduction.
S. As environments change, organisms that can adapt their behaviour, structure and physiology to such changes are more likely to survive.
The correct answer is (b) .
- The paragraph starts with 'Q', introducing the concept of organisms adapting to the concept of organisms adapting to their environments.
- 'S' follows, explaining that those who adapt are more likely to survive.
- Then, '
' describes national selection as the driving force behind adaption. - Finally, 'P' concludes by stating that these adaptations can lead to evolutionary changes
