Correct answer: D
To find the Excess-3 code for decimal 85, add 3 to each digit. The digit 8 becomes 11 (binary 1011), and the digit 5 becomes 8 (binary 1000). The resulting code is 1011 1000. Counting the ones gives four, so statement (i) is false. The least significant bit is 0, making statement (ii) false as well.
