A way of representing information using only two options.

• A. Binary
• B. ASCII
• C. Decode
• D. Encode

Answer: (A)

Two-option representation points to binary. In computing, data is stored as bits, each of which can be in one of two states, typically represented as 0 or 1. By combining many bits, you can represent numbers, letters, images, and more. This two-state system underpins how digital circuits work—on or off, true or false. ASCII is related but is a specific encoding scheme that uses binary patterns to represent characters, not the general idea of using two options. Encode and decode describe the actions of turning information into or out of a representation, rather than the way information is inherently represented. So the best answer is binary.
