Title A & B is written as A & B inside the title tag.
The HTML is assembled from the fields you fill. Empty optional fields are left out. A canonical URL, an Open Graph image, an Open Graph URL, and a Twitter image must be absolute http or https URLs. The page does not request those URLs.
The title can be up to 200 characters and the description up to 500. Open Graph type is website, article, or none. Twitter card is summary, summary_large_image, or none. A Twitter title without a card is rejected.
