Final answer:
Jupiter refuses to give fire to humans because he fears they would become as strong and wise as the gods, posing a potential threat to the gods' superiority.
Step-by-step explanation:
The passage that most strongly explains why Jupiter will not give fire to man is option B) "If men had fire they would soon be as strong and wise as we who dwell on Olympus." This statement highlights Jupiter's concern that humans might become too powerful and potentially equal to the gods if they possess the ability to use fire. This rationale is based on the fear of human advancement and the potential threat it could pose to the gods' status and power.
