The best answer is (D) All organisms share a genetic code that allows one organism to express a gene from another organism.

Here's why:

(A) While it's true that all organisms have the capacity to grow and reproduce, this doesn't necessarily support the claim that they all descended from a common ancestor. It's a basic characteristic of life, but it doesn't provide evidence of common descent.

(B) Not all organisms use oxygen for cellular respiration in mitochondria. Some organisms, like anaerobic bacteria, don't use oxygen at all. Moreover, while the endosymbiotic theory suggests that mitochondria were once free-living prokaryotes, this doesn't directly support the claim of a common ancestor for all organisms.

(C) Different species having specific traits and adaptations that allow them to succeed in diverse environments is evidence of evolution and natural selection, but it doesn't directly support the claim of a common ancestor.

(D) All organisms sharing a genetic code that allows one organism to express a gene from another organism is strong evidence of common descent. This is because the genetic code is universal, meaning it's the same in all organisms. This suggests that all organisms share a common ancestor from which this genetic code originated.
