B

The answer to the following question is B, and we examine the numbers first by the number of digits they have, 535; 3 digits 2407; 4 digits 4145; 4 digits 6643; 4 digits 14,494 5 digits, We then know 535 is the smallest while 14494 is the biggest. We sort the other numbers based on their first digits, then look at the second digit and so on. 2<4<6, thus the order is 535; 2407; 4145; 6643; 14,494
