Concept:Grammatical gender classifies nouns as masculine or feminine based on biological sex.
Explanation:The word "Earl" refers to a British man of high social rank.
The feminine counterpart of "Earl" is "Countess".
A Countess is either the wife of a count or earl, or a woman of high social position.
For example: The Countess assisted the Earl in his duties.
Option A, "Lady", is a general term for a woman of high class but not the specific feminine form of "Earl".
Option C, "Earless", means lacking ears and is unrelated.
Option D, "Goddess", means a female deity.
Therefore, only "Countess" correctly pairs with "Earl" as the feminine gender.
Answer:Option B: Countess
