Which one of the following pairs is not correctly matched ?

The pair 'Thailand: Ringgit' is incorrectly matched. The official currency of Thailand is the Thai Baht (THB) [t4]. The Ringgit (MYR) is the official currency of Malaysia [t5][t6]. The other pairs are correctly matched: Brazil's currency is the Real (plural: Reais), denoted as BRL [t4][t6]. China's currency is the Yuan, also known as the Renminbi (CNY) [c1][c3][t6]. Mexico's currency is the Peso (MXN), specifically the Nuevo Peso [t6][t8]. Modern currencies are authorized by their respective governments as a medium of exchange [c5]. While the Ringgit is a major trade currency in Southeast Asia, its jurisdiction is strictly Malaysia, whereas Thailand has maintained the Baht as its legal tender [t4][t5].
