Imagine you are developing an algorithm to calculate the total cost of a purchase order that contains several items. The cost of each item and the tax rate is known. The standard shipping charge for the entire order is $4.95, and the special delivery charge is $19.95. In addition, there is no tax on the shipping cost. Which of the following is the correct pseudocode for the required algorithm?
A) For each item on the purchase order:
Order cost = order cost + item cost
Total purchase order cost = order cost + tax rate + 4.95
B) For each item on the purchase order:
Order cost = order cost + item cost
If standard shipping
Shipping cost = 4.95
Else
Shipping cost = 19.95
Total purchase order cost = order cost * tax rate + shipping cost
C) If standard shipping
Shipping cost = 4.95
Else
Shipping cost = 19.95
For each item on the purchase order:
Order cost = order cost + item cost + shipping cost
Total purchase order cost = order cost * tax rate
D) If special delivery
Shipping cost = 4.95
Else
Shipping cost = 19.95
For each item on the purchase order:
Order cost = order cost + item cost
Total purchase order cost = order cost * tax rate + shipping cost

Option B is the correct pseudocode as it correctly adjusts the shipping cost based on whether standard or special delivery is chosen. It also calculates the order cost by adding the cost of each item and then calculates the total purchase order cost by multiplying the order cost with the tax rate and adding the shipping cost. Option A does not take into account the shipping cost correctly. Option C calculates the total order cost incorrectly by adding the shipping cost to the order cost for each item. Option D incorrectly assumes that special delivery always incurs a higher shipping cost.
