Two ways possible - creating inside admincp or writing directly in product-yourproductname.xml

It is the same way in vb4 and in vb5 so you should read https://forum.vbulletin.com/blogs/joe-d/3932614- (not all parts the same but for options it is) and for debug modus https://forum.vbulletin.com/forum/vb...=1#post3605592 (in vb4 only one config.php exists)

My advice:
Create new product as described above, add options /optiongroups and export after every step the product-...xml. So you can see the relevant xml-syntax at the end of this file
<options><settinggroup name=""..><settings varname="">
and
<phrases><phrasetype><prase name="">
with naming conventions for optiongroup and option
Examples <phrase name="setting_SETTINGSVARNAME_desc/_title" and <phrase name="settinggroup_SETTINGGROUPNAME"
And at this point check also help text for your options and so on


With this you can write it later directly to xml. And as an example I used often as reference download the product YaAS 4.0.9 (Yet another award system) and read the xml with implementations of different option types.
