Answer:
The correct answer is The customer's available credit should be checked.
Explanation:
A credit is a financing operation where a person called 'creditor' (usually a financial entity), lends a certain monetary figure to another, called 'debtor', who from then on, guarantees the creditor that he will return this requested amount in the previously stipulated time plus an additional amount, called 'interest'.
According to some authors in economics, credit represents a change that acts in time, rather than in space, so it is also considered "to alternate money from the present, for money in the future." The word derives from the Latin credititus, which means ‘trust’, therefore, a credit is the right of the creditor to receive from the debtor, the amount borrowed.
