Solution

The correct option is C Only statement 3 is correct.
In the process of evolution, it is not necessary that to pave way for a new species to develop, the existing species needs to perish. The newly generated modifications may be naturally selected or they might have developed by mere coincidence, chance or an accident (genetic drift). These changes may or may not help the species to adapt better or triumph the existing one in terms of complexity or characterstics.
Natural selection and genetic drift are the forces of evolution which can give rise to development of new species.

11. Consider the following statements,

1] Genetic variation is the cornerstone of evolution, without which there can be no natural selection, and so a low genetic diversity decreases the ability of a species to survive and reproduce.

2] Greater the genetic diversity, the better is the population's ability to respond to pressures such as climate change and diseases.
