The excerpt that supports the deduction of humans requiring the sun to survive would be:
d). “and from it descends all vital force.”
"In Praise of the Sun"
The above quote most effectively backs the idea of the significance of the sun for human existence and survival by showing that it degenerates its significant force to provide heat to humans.

Thus, option d is the correct answer.
