(A) Dollar
(B) Takka
(C) Rupee
(D) Lira
🧠 Explanation:
- The official currency of Sri Lanka is the Sri Lankan Rupee, abbreviated as LKR.
- It is symbolized as "Rs" and is used in all financial and commercial transactions across the country.
- Sri Lanka is not associated with currencies like the Dollar (used in the USA), Taka (used in Bangladesh), or Lira (used in Turkey).
- Therefore, the correct answer is "Rupee," which is unique to Sri Lanka as the Sri Lankan Rupee.
