The correct answer is Parents pass their physical traits to their offspring; those offspring with traits that help them survive in their environment are able to reproduce.
Explanation:
The modern theory of evolution explains the mechanisms that make organisms change. One of the main ideas this theory proposes is that organisms with traits that help them survive or reproduce have higher chances to pass their genes and traits to new generations. This mechanism makes certain traits to be favored and contributes to the evolution of organisms because after multiple generations certain traits will prevail while others will be eliminated.
Moreover, this theory specifies genes in an organism are not acquired or modified during its life but these are the results of the traits passed to the organism by its parents and evolution occurs only after a long time or multiple generations. According to this, the first option is the correct one.
