B) favors organisms well adapted to the environment.
Not positively sure about my answer because I haven't read about this since two years ago in biology.
The correct answer is option C, that is, epoch.
An epoch refers to a time unit. An epoch in geological time scale refers to a subdivision, which is lengthier than an age but briefer in comparison to a period. The present epoch is the Holocene epoch of the Quaternary period.
The two or more periods form a geological era, two or more eras form an eon and is the largest division of the geologic time.

There are many types of frogs thus there are a lot of scientific names also, such as Rana draytonii or Atelopus zeleki. But the common scientific name or order for frogs is called Anura.
The answer is B) DNA in the nucleus.
