ABCD Analysis This question tests the knowledge of bank card interest calculation. If you select the minimum repayment amount for a credit card or use the card beyond the approved credit limit, you will not be eligible for the interest-free repayment period. Cash withdrawals with credit cards and overdrafts with quasi-credit cards do not enjoy the interest-free repayment period and minimum repayment amount. All four statements in this question are consistent with the meaning of the question.
