In terms of natural selection, what is the best description of an organism that is fit?

-The organism is physically stronger than competing organisms.

-The organism is physically stronger than organisms of a different species

-The organism is better able to survive and pass on traits to offspring than competing organisms.

-The organism is a member of a population in which every member survives without competing

Option C, The organism is better able to survive and pass on traits to offspring than competing organisms.

Explanation:

According to Darwin's theory of natural selection, an organism is said to fit if it is capable to survive against all the adversities in its surrounding environment and habitat which otherwise have restricted all other organism from surviving. Also a fit organism is able to reproduce fertile and viable offspring. For example - occurrence of fit dark colored moth during the industrial revolution while the light colored moth were unable to survive

Hence, option C is correct

In terms of natural selection, what is the best description of an organism that is fit?

Natural selection entails organism that best fits in an environment and it could only be known as a result of survival rate of such organism. Those that survives difficult periods are best describes as fit
