Would anyone be able to help me with this question?

Answer:
A woman who dies at 95 after giving birth to 6 healthy children.
Explanation:
"Evolutionary Fitness" is part of Charles Darwin's Evolution Theory. According to this, an organism's biological fitness is crucial in the evolution of its genes.
Biological Fitness refers to the ability of an organism to produce a "healthy" or "viable" offspring. This situation can be achieved through various adaptations, such as living longer in order to have more mates. This will then give the organism more off springs.
Thus, it affects on how the off springs will survive and have the ability to reproduce in the future (Evolutionary Fitness).
Among the choices above, "A woman who dies at 95 after giving birth to 6 healthy children" has the highest evolutionary fitness because she lived longer and produced healthy off springs. Her off springs also didn't die before reaching adulthood, thus her off springs will also have the chance to have high level of evolutionary fitness.
