Regarding natural selection, the correct statement is:
D. Es la herencia de características favorables en un ambiente determinado.
This statement is accurate because natural selection is the process by which organisms that are better adapted to their environment tend to survive and reproduce more successfully than those that are not as well adapted. Over time, this leads to the inheritance of advantageous traits within a specific environment. It is not a process that occurs in environments favoring all individuals, nor is it solely a mechanism that develops in the communities of ecosystems. Natural selection does not occur after adaptation, but rather it is the driving force behind adaptation as individuals with beneficial traits are more likely to pass those traits to future generations, leading to a better fit with their environment over time.
