You can't use another tag inside options tag. But you can do something like:

<select>
 <option>&sup1;</option>
 <option>&sup2;</option>
 <option>&sup3;</option> 
</select>

This &sub1, &sub2, &sub3 is only possible for 1, 2 and 3.

You can write other numbers using codes from here: Superscript Chart

Or you can use this website to get the unicodes of alphabets: Unicode Character Search
