Answer:
C) discharged
Step-by-step explanation:
Since Flora's crops were destroyed by bad weather, her contract obligation is discharged due to a clear impossibility to perform. This means that even if Flora tries to perform her part of the contract, she will not be able to do it, at least not according to the recent circumstances. This type of actions are caused by acts of God (legal way to say natural forces), e.g. floods, fires, hurricanes, etc., and the parties involved in the contract are not responsible for them.
