If intelligence is so useful, why do so few species have it?

Explanation:

Could intelligence simply be unlikely to evolve? Unfortunately, we can’t study extraterrestrial life to answer this question. But we can study some 4.5 billion years of Earth’s history, looking at where evolution repeats itself, or doesn’t.

I think the correct answer from the choices listed above is option C. it is the capsule that represents the sporophyte stage of the bryophytes. This structure is the reproductive structure that releases spores in bryophytes. Hope this answers the question. Have a nice day.
