If S has a size code of 003, what is the code for size M?

In the context of size coding, if size S is represented by the code 003, the code for size M is sequentially higher than that for size S. Size coding typically follows a numeric or alphabetical order based on the size increments.

Given that size S is 003, size M commonly follows as the next increment in the sequence. Therefore, size M is designated as 004. This pattern reflects a logical progression in size codes, where each increase in size corresponds to an increase in the code number.

In this case, the increasing order means S (003) is smaller than M, which is correctly represented by 004. The other choices in the options do not follow this logical sequence, as they represent either the same size or go backward in the size progression.
