What is the official currency of Sri Lanka?

The correct answer is the Sri Lankan Rupee (LKR), the official currency issued and regulated by the Central Bank of Sri Lanka. Like several of its South Asian neighbours, Sri Lanka adopted the rupee denomination after independence from British colonial rule, and the Sri Lankan Rupee has circulated as legal tender since the country transitioned away from the earlier Ceylonese currency system in the mid-twentieth century. Each rupee is subdivided into 100 cents, and the Central Bank of Sri Lanka is responsible for issuing both currency notes and coins as well as setting monetary policy. This question is deliberately built around a common trap: the term "rupee" is shared across multiple South Asian currencies, which makes it easy for candidates to select the wrong country's currency if they rely on the word alone rather than the specific national qualifier. The Indian Rupee, option A, is the currency of India and, while historically and culturally linked to Sri Lanka through trade and geographic proximity, is a completely separate legal tender not used in Sri Lanka. The Nepalese Rupee, option B, belongs to Nepal, a Himalayan nation with no geographic connection to Sri Lanka, and is included here purely as a plausible distractor exploiting the shared "rupee" naming. The Maldivian Rufiyaa, option D, is the currency of the Maldives, an island nation in the same broader Indian Ocean region as Sri Lanka, which sometimes causes confusion because both are island nations near India, but "Rufiyaa" is a distinct denomination unrelated to the rupee family. A common exam confusion is assuming all Indian Ocean or South Asian island nations share currency names; in reality, each has issued its own distinct national currency since independence.
