Answer:
The answer is: D) continue flying until the lease expires and then drop the run.
Explanation:
Currently Cold Duck Airlines is losing money:
It only gets $1,000 in revenue per flight but spends $1,150 per flight (net loss of $150 per flight).
They should continue flying only until the lease contract expires. Usually lease contracts apply penalties if they are terminated early. We don't know the penalty amount but still it is never good to breach a contract.
