The binary number '1010' represents the decimal number 10. Each position in a binary number corresponds to a power of 2, starting from the rightmost digit. So, in '1010', the leftmost '1' represents 23 (8), and the second digit '0' represents 22 (0), the third '1' represents 21 (2), and the last '0' represents 20 (0). Adding these together (8 + 0 + 2 + 0) gives us 10. The other options either represent different binary values or do not correspond correctly to '1010'.
