Choose the feminine gender of 'Sire'-

The feminine gender of "Sire" is "Dame."

Explanation:

"Sire" is a term used to address a male monarch or a person in authority, often in a feudal or historical context. It's equivalent to addressing someone as "Lord" or "Sir." The corresponding feminine term is "Dame," which is used for a woman holding a non-hereditary title conferred by a sovereign state, the female equivalent of a knight. "Siress" and "Sirent" are not standard terms in English for the feminine form of "Sire." "Dane" is unrelated, referring to a person from Denmark. Therefore, "Dame" is the appropriate feminine counterpart to "Sire."
