Answer:
A) Accrual principle
B) Cost principle
C) Economic entity principle
Explanation:
Accrual principle: indicates that accounting transactions should be recorded in the accounting periods when they actually occur, rather than in the periods when there are cash flows associated with them.
Cost principle: according to this concept, a business should only record its assets, liabilities, and equity investments at their original purchase costs.
Economic entity principle: implies that the transactions of a business should be kept separate from those of its owners and other businesses.
