Explanation:

Assuming the following list of inputs:

V. The amount payable after discount  

Possible options for the

a) I, II, and III

c) II, IV, and V

d) II and IV  

For this case we want to calculate the amount payable by the customer after the discounts.

And for this case is always necessary the value of the purchase so option II is true. The percent of discount is given so then option I is not true since we know this value.

The option III is not required since the discount is based on the info and if the customer have ID card so then this value is not necessary.

For option IV is necessary know the ID card in order to identify if the person have a permanent or non permanent card in order to apply discounts, this information is useful

And for the last option V that's not an input, since represent the output desired.

So then the correct options are II and IV
