Choice "B" is correct. The batch includes five documents representing invoices 101 through 105.Choice "d" is incorrect. The number 100 is a hash total that is the sum of the product id numbers.Choice "c" is incorrect. The number 105 is a sum of the unit prices of the items on the included invoices. Since this total has no real meaning, it would be a hash total that is used to validate batch data entry.Choice "a" is incorrect. The number 750 is a sum of the number of items sold. Since there are different items, this total has no meaning alone but could be a hash total used as a data input control in batch data entry.
