Binary code uses alphanumeric characters to represent all values.

• A. True
• B. Not at all
• C. Alphanumeric characters
• D. False

Answer: (D)

Binary uses base-2, so values are represented with just two symbols: 0 and 1. Each bit is either 0 or 1, and groups of bits (like a byte) encode numbers, letters, and other data. The statement says binary uses alphanumeric characters to represent all values, which would require many different symbols. In fact, while alphanumeric characters can be encoded into binary, the binary code itself is still only 0s and 1s. So the statement is false.
