Explanation: Binary numbers operate on a base-2 system, meaning each digit can only be a 0 or a 1. Each position in a binary number represents a power of two, increasing from right to left. For the quantity TWO: * The rightmost digit represents 2^0 (which is 1). * The second digit from the right represents 2^1 (which is 2). * The third digit represents 2^2 (which is 4), and so on. In option A) **0010**: * The rightmost '0' represents 0 * 2^0 = 0 * 1 = 0. * The second '1' from the right represents 1 * 2^1 = 1 * 2 = 2. * The remaining '0's contribute nothing to the value. Adding these together (0 + 2 + 0 + 0) gives a total of 2. Options B) 0002, C) 2000, and D) 0020 are incorrect because they contain the digit '2'. By definition, binary numbers can only consist of '0's and '1's.
