Question

Can someone check my answer?

Which statement best supports the fact that natural selection occurs in the marine environment?

Few marine organisms survive when the ocean environment is unstable.
Genetic mutations occur more frequently every time the ocean environment changes.
(Advantageous traits become more common in each subsequent generation.)
The fossil record provides a sample of every marine organism that has ever lived.

I think C

Answer 1

I also think that the answer is C as it is the only one that is actual evidence 

Answer 2

The correct answer is "Advantageous traits become more common in each subsequent generation".

Step-by-step explanation:

Natural selection is the process at which evolution is based on, which consist of the organisms having advantageous traits are more likely to survive. This is known as survival of the fittest, and if a marine organism is analyzed during its evolutionary tree, it will be noticed that advantageous traits become more common in each subsequent generation. This evidence supports natural selection and predicts that it is continually happening in the marine environment.
