Answer:
A. All checks require two signatures.
Step-by-step explanation:
Internal controls refer to the checks and balances that an organization puts into place to ensure its financial transactions' integrity. They are the measures and regulations that safeguard against fraudulent transactions, especially in the finance department. Internal control protects business assets from theft and misuse by malicious employees.
Requiring all transactions to be approved by a senior officer is a control measure that would have prevented Tyler Jones from succeeding in stealing. In this case, the check would have to be signed by a second person. The second signature serves as an approval.
