Which of the following statements about natural selection are correct?
(i) Tends to increase the characters that enhance survival and reprocution
(ii) Inviduals with better adaptive ability leave more progeny
(iii) Was considered as mechanism of evolution by Darwin

Options

A. i,ii and iii
B. i and ii only
C. iii only
D. i and iii only

Answer

To determine which statements about natural selection are correct, let's analyze each statement step by step:

1. **Statement (i): Tends to increase the characters that enhance survival and reproduction.**
- Natural selection is a process where individuals with traits that are better suited to their environment tend to survive and reproduce more than those without such traits. This means that over time, the traits that enhance survival and reproduction will become more common in the population. Therefore, this statement is correct.

2. **Statement (ii): Individuals with better adaptive ability leave more progeny.**
- Adaptive ability refers to how well an organism can adjust to its environment. Those individuals that are better adapted to their environment are more likely to survive and reproduce successfully. As a result, they will leave behind more offspring. Thus, this statement is also correct.

3. **Statement (iii): Was considered as a mechanism of evolution by Darwin.**
- Charles Darwin proposed the theory of natural selection as the mechanism for evolution. He suggested that natural selection is the process through which species evolve over time due to the differential survival and reproduction of individuals with favorable traits. Therefore, this statement is correct as well.

In conclusion, all three statements about natural selection are correct.

**Final Answer: All statements (i), (ii), and (iii) are correct.**
