The answer is clearly "C" because an adaptive feature is a feature in which a living organism has adapted to, for example:
Millions of years ago, fish and other water creatures evolved to breathe on the surface, and not just in the water. However, this process took many years to adapt to the climate.

I know that this is a gene so I assume, by the wording that this is a length of DNA from another human. Can't particularly explain this very clearly though, sorry. You can read more about it here though by searching about it, sorry I can't put the link as my answer will be removed.
I hope this helps you but if it does not, don't be mean! Message me and I will try my hardest to resolve my answer! :D
In order to add one gram of mass, the whale must consume a sufficient amount of energy. The energy transferred to the fourth trophic level is 0.1⁴ = 0.0001
We divide the mass to be gained by the energy obtained per unit mass, to find the total mass to be eaten:
1 / 0.0001 = 10,000 grams of phytoplankton must be consumed to add one gram of mass.
