The correct answer is: Option C. Serious curtailment of income.
The objective of a business company is to have a profitable business plan by offering goods or services promising of demand. When these goods or services are not requested enough to generate the required income for maintenance of the business' infrastructure, then not only the business plan becomes obsolete, but the company ends up hanging on the verge of failure.
It is hard to recover from this mistake if production has already been set to meet with the business plan estimates since the excess produce would simply be stored and not sold.
