Final answer:
Juno offers Aeolus a reward in exchange for his assistance, indicating a transactional approach rather than using threats, commands, or persuasion.
Step-by-step explanation:
In lines 71-80, the action Juno takes when asking Aeolus for help is B) She offers him a reward in exchange for his help. Juno employs negotiation rather than threats or commands, and her approach is based on the idea of a transaction, where Aeolus's assistance is compensated with a reward. This is contrasted with options where Juno could have used coercion or persuasion through kind words, neither of which are indicated in the selected lines.
