Explanation:
Judging from the formula used in computing the GDP,option A relates to household consumption as the new textbook is not for resale.
Option B also points to household consumption expenditure,as the cup of coffee is for household usage.
Option C does not have a place in the formula as it is not a payment for a good or service.It is a payment that cannot be tied to any transaction.Hence,option C is your best bet.
