The correct answer is option 1: Venezuela. Bolivar is the monetary unit of Venezuela. It is named after Simón Bolívar, who was a Venezuelan military and political leader during the early 19th century. The bolivar has been the official currency of Venezuela since 1879. It is symbolized by the abbreviation "Bs" or "Bs.S", depending on the specific currency exchange rate. The bolivar is further divided into smaller units called centimos, but due to hyperinflation in Venezuela, the centimos are rarely used in everyday transactions. It is important to note that the Venezuelan bolivar has experienced significant devaluation in recent years, leading to economic instability in the country. As a result, the government has introduced new versions of the currency in an attempt to stabilize the economy and curb inflation.
