What is the difference in value if a Dutch diamond dealer's expenses increase by 4,717 with respect to the currency used?

The correct answer reflects that if the diamond dealer's expenses increase by EUR 4,717, it means that the dealer will need to spend an additional amount in euros to cover this increase. This directly impacts the value of expenses in the currency they are dealing with, which is euros.

In the context of currency, stating "EUR 4,717 more" signifies the increase in the cost structure that the dealer must absorb. Since the dealer's expenses have risen, they are facing a higher financial obligation in the same currency in which their expenses are denominated.

The other options mention ZAR (South African Rand) or imply a reduction in value, neither of which aligns with the fact that the expenses have increased by a specific amount in euros. There is no indication that the transaction involves currency conversion or a reduction in expenses, making the answer focused exclusively on the direct increase in expenses clear and accurate.
