From the given sentence, form a feminine noun from the masculine word given:
The Duke Of Wales inaugurated the function.The answer to the given sentence is Option C, Duchess.
As per the question, the sentence would have the male gender noun to be replaced by the feminine noun, after dropping the vowel, and then adding the syllable ‘-ess’. Here, we are dropping the ‘e’ from the noun and adding the syllable to get Option C, ‘Duchess’, which is the feminine counterpart of the noun and will mean the same, being the ruler over a certain area.
Option A, Empress and Option B, Queen, are actually feminine counterparts of Emperor and King, respectively and are hence wrong answers.
Thus, Option C, Duchess, is the correct answers.
