Final answer:
Delilah may be required to pay no more than $50 for unauthorized charges on her stolen debit card if she reports it to the bank within 2 business days.
Step-by-step explanation:
Delilah may be required to pay no more than $50 (option B).
According to the Electronic Fund Transfer Act (EFTA), if Delilah reports the theft of her debit card to the bank within 2 business days, she will be liable for a maximum of $50 in unauthorized charges.
If Delilah reports the theft after 2 business days but within 60 calendar days, her liability can increase to a maximum of $500 (option C).
However, if Delilah waits more than 60 calendar days to report the theft, she could be held responsible for the full amount of unauthorized charges (option D).
