Options are typically "optional" add-ons to Products, if your options are required for the Product, such as size or colour, you should use the variations tab instead.
Product options allow you to offer optional add-ons to a Product, or capture extra information from your customer, such as a message for engravings, a file upload for printed t-shirts, or a date selection for events.
