Answer is Right!
Answer is Wrong!
The correct answer is: D. BG
The top-level domain (TLD) for Bulgaria is .bg. It was introduced in 1995 and is administered by the Bulgarian Academy of Sciences. The TLD is used for all types of websites, including commercial, personal, and government websites.
The other options are incorrect because they are not top-level domains for Bulgaria. A. BU is the ISO 3166-1 alpha-2 code for Bulgaria, B. BR is the ISO 3166-1 alpha-2 code for Brazil, and C. BL is the ISO 3166-1 alpha-2 code for Saint Barthélemy.
