A) "Hmm. I guess that's just the way it is."
B) "Humans require so many more complex physical skills than do other species that it takes them a much longer time to develop."
C) "It's part of God's design."
D) "Humans' environments are more complex and varied than those of other species. An extended developmental period allows us to acquire the flexibility to adapt to such environments."

Among the given options, choice D is the most accurate explanation for why human childhood is much longer than that of other species. Humans are born with fewer innate abilities than other animals, and human environments are much more diverse and complex. Hence, an extended developmental period enables humans to acquire the cognitive, social, and physical skills necessary for survival and adaptation.
