Since its a global item to update we need behavior code

That is the only code you need so far.

Detailed Instructions

Navigate cog icon > Manage apps > under SCRIPTRUNNER > Behaviours > Add Behaviour > Edit your new behaviour > Add Mapping to your project and issue types > attach list A field by Add Field > Add server-side script > paste the one liner:

getFieldByName('YourListBName').setFormValue(-1)

The code is really self-explanatory. The behaviour script is triggered whenever the attached field (List A) has changed, the script "get"/search for a field named "YourListBName" then set the field value to "-1", which means "none".
