What are the different Unicode encoding standards mentioned?

The correct choice highlights the three main Unicode encoding standards: UTF-8, UTF-16, and UTF-32. These standards are critical for representing text in computers and enable the consistent encoding, representation, and handling of text expressed in most of the world's writing systems.

UTF-8 is particularly widespread because it is compatible with ASCII and can represent any character in the Unicode standard using one to four bytes. This flexibility allows for efficient storage of text while still enabling the use of the full range of Unicode characters.

UTF-16, on the other hand, uses two or four bytes for each character. It is often used in environments where larger character sets are common, such as in programming and for languages with complex characters.

UTF-32, while less common in practice due to its fixed length of four bytes for all characters, simplifies certain programming tasks since all characters take the same amount of storage space, making it easier to calculate the positions of characters.

The mention of other options helps clarify why they are not relevant. Options that include encoding formats such as ASCII or Base64 do not pertain specifically to the Unicode encoding standards. In particular, ASCII is a character encoding standard based on the English alphabet and does not encompass the broader range of characters covered by
