Why is option A rejected?
I feel that option A takes care of reducing the costs in future, making the business sustainable. However, I agree that we cannot comment about the degree of savings.
But, OA C also doesn't talk about the quantum of customers. The revenues generated on account of exceptionally high costs may also be at a lower level if customers are few.
So, what is the basis of choosing option C wrt A?
