Assertion: The variety of life on Earth can be explained by evolution, which has strong scientific backing.
Reason: Natural selection, a process by which organisms that are more adapted to their environment tend to live and reproduce more successfully than other species, is what causes evolution.
Assertion and reason are both true, and reason is an accurate account of assertion.
Both assertion and reason are accurate, but reason does not adequately explain assertion.
The assertion is correct, but the reasoning is incorrect.
Both the assertion and reason are incorrect.
A widely accepted scientific theory that explains how the variety of life on Earth came to be is evolution. Numerous pieces of evidence from numerous scientific disciplines, including genetics, geology, paleontology, and others, support this theory. The explanation given is also accurate. One of the main mechanisms of evolution is natural selection. It explains how some members of a population are more suited to their surroundings than others and, as a result, are more likely to survive and pass on their favorable features to their progeny. This process can eventually result in the birth of brand-new species or the evolution of already-existing ones. Therefore, the assertion and reason are both accurate and complement each other in explaining the meaning of evolution.
Option a is the correct answer.
