Credit cards enable borrowing, not direct exchange as money

Steps:

• Define money as a medium of exchange accepted for goods/services, like fiat currency.
• Identify A (banknote) and C (coin) as legal tender, directly usable as money.
• Classify B (cheque) as a negotiable instrument representing a claim on bank deposits, functioning as money in transactions.
• Determine D (credit card) as a tool for accessing credit lines, not an asset or claim transferable as money itself.

Why the correct option is correct:

• Credit cards facilitate deferred payments via loans, not serving as a store of value or medium of exchange per monetary definitions (e.g., M1 includes currency and deposits, excluding credit).

Why the others are wrong:

• A: Banknotes are fiat currency, legal tender for transactions.
• B: Cheques transfer demand deposits, acting as money substitutes in payment systems.
• C: Coins are metallic fiat money, widely accepted for exchange.

Final answer: D
