Select the set in which the numbers are related in the same way as the numbers of the following sets. (Note: Operations should be performed on whole numbers without breaking them into their constituent digits. For example, consider 13. Operations such as adding to/subtracting from/multiplying 13 can be performed only on 13. Breaking 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
