Topic: Gender (লিঙ্গ),

Best Answer Explained in Below-:

The term "signor" is an Italian word that refers to a gentleman or sir, often used to show respect. Its feminine counterpart is "signora," which translates to "madam" or "lady" in English. This distinction between masculine and feminine forms is common in many languages, including Italian, where nouns and titles often have specific endings based on gender.

Examining the other options:

- **B) signonr**: This option appears to be a misspelling of "signor" and does not have any standing as a term in Italian.

- **C) signoress**: This is not a recognized term in Italian or in English and seems to be an attempt to create a feminine form similar to "actress," which does not apply here.

- **D) signorer**: This is not a valid form in Italian. The suffix "er" does not correspond to the feminine or masculine forms in the context of Italian nouns.

Therefore, the correct answer is **A) signora**, as it accurately represents the feminine gender of "signor." Understanding gendered nouns in Italian reveals the importance of these distinctions in respectful address, demonstrating the language's grammatical structure.
