Cost accounting is based on-

Single accounting system
Indian book-keeping system
Double accounting system
None of the above

The correct answer is: C. Double accounting system

Cost accounting is a system of accounting that is used to track the costs of goods and services. It is based on the double accounting system, which is a system of accounting that records both the debits and credits for each transaction. This allows businesses to track their costs more accurately and to make better decisions about their operations.

The single accounting system is a simpler system of accounting that only records the debits for each transaction. This system is not as accurate as the double accounting system, and it does not provide as much information about a business’s costs.

The Indian book-keeping system is a system of accounting that is used in India. It is based on the double accounting system, but it has some unique features that are not found in other systems of accounting.

None of the above is not the correct answer.
