organisms that conserve energy by not reproducing.
B.
organisms that have the longest lives.
C.
only the strongest and fastest organisms.
D.
organisms that survive long enough to reproduce.

D, organisms that survive long enough to reproduce.

C and D are the best answers. Adaptations and skills other than speed and strength contribute to an organism's survival too, so that means it isn't C. Natural Selection is about how an organism must have useful traits to survive to reproductive stage and  successfully reproduce, so it would definitely be D.
