Answer: B D E
I agree with B,D and E as what an example provided on the link.
I would say B,D, E as right answer.
Ref: https://meetanshi.com/blog/create-custom-customer-attribute-in-magento-2/
This is a really odd question…
You would only need to use get connection to start like: C $this->moduleDataSetup->getConnection()->startSetup();
B is a given $customerSetup->addAttribute()
D is used to specify that its used in the admin $notesAttribute->setData(‘used_in_forms’, [‘adminhtml_customer’]); Once its been added.
Ive never used either E or A. Id go for A because the ddl cache is a thing https://devdocs.magento.com/guides/v2.4/config-guide/cli/config-cli-subcommands-cache.html
So i reckon like it says ABD is correct
