Consider the following pairs : 1. ABN Amro Bank :USA 2. Barclays Bank :UK 3. Kookmin Bank :Japan Which of the above pairs is/are correctly matched ?

ABN AMRO is a Dutch bank with headquarters in Amsterdam and origins in the Netherlands, not the USA, so pair 1 is incorrect [1]. Barclays is a long-established British bank headquartered in the United Kingdom (London), so pair 2 is correctly matched [2]. KB Kookmin Bank (Kookmin Bank) is headquartered in Seoul and is a South Korean bank, not Japanese, hence pair 3 is incorrect [3]. Therefore only pair 2 is correctly matched. This conclusion uses the cited sources for the country of origin of each listed bank and standard knowledge of their headquarters and national origins.
