You’re setting up a product feed in Merchant Center for the first time, and you realize you don’t have availability for each product. What will happen if you try to upload the feed in Google Merchant Center?

Availability is an optional attribute, so Google’s system will flag it as a warning for you to resolve in the future.
Availability is not an attribute in the product feed, so Google’s system will disapprove the feed.
Availability is a required attribute, so Google’s system will disapprove the feed until all required attributes are included.
Availability is a required attribute, so Google’s system will flag it as a warning for you to resolve in the future.

The correct answer is:

Availability is a required attribute, so Google’s system will disapprove the feed until all required attributes are included.
