Answer: B : No, approval by an individual other than the requestor establishes greater accountability over inventory.
Explanation:
The purpose of reviewing the material requisition slips is to ensure that there is greater accountability in inventory acquisition and this is why it is important that someone else apart from the person requesting approves the inventory request as it will reduce chances of fraud.
If the person requesting could also approve, there is a chance that inventory that is not needed will be ordered and then used for purposes other than to benefit the business but to benefit the person who requested it.
