Correct Option: (A) EDIC

Explanation

In computer science, character encoding schemes (often referred to as computer codes) are used to represent text in computers by assigning numeric values to characters.

• ASCII (American Standard Code for Information Interchange): A standard character encoding scheme for electronic communication. It uses 7 bits to represent characters:

  $$2^7=128\text{ possible characters}$$

• BCD (Binary Coded Decimal): A class of binary encodings of decimal numbers where each decimal digit is represented by a fixed number of bits, usually four.

  $$1\text{ decimal digit}=4\text{ bits}$$

• EBCDIC (Extended Binary Coded Decimal Interchange Code): An 8-bit character encoding used primarily on IBM mainframe and midrange computer operating systems.

  $$2^8=256\text{ possible characters}$$
