Select the most appropriate option that rectifies the error(s) in the following sentence.
One must do his/her duty proparly.

Correct option is D

Option (d) correctly rectifies the errors in the sentence.
Explanation: The original sentence contains spelling errors in "proparly" (which should be "properly") and incorrect pronoun usage. When using the pronoun "one," the possessive form "one's" should be used, not "his/her." The word "duty" is correctly spelled, and "properly" corrects the spelling error from "proparly."
Correct Sentence: One must do one’s duty properly.
Grammatical rule used:
· Pronoun agreement: When using the indefinite pronoun "one," the corresponding possessive pronoun should be "one’s," ensuring consistency.
· Spelling correction: "Properly" is the correct spelling, meaning in a suitable or correct manner.
Example: One should always follow one’s principles.
