Correct option is A
The correct option to fill in the blank is (a) cite.
“To cite” means to reference sources formally in a standardized style—exactly what the professor is urging. (Hindi: संदर्भ देना/उद्धरण देना).
Example: You must cite journal articles in APA format in the bibliography.
Explain why other options are incorrect.
· quote: to reproduce exact words (Hindi: शाब्दिक उद्धरण देना); related but not the act of formatting references.
· proscribe: to forbid/ban (Hindi: प्रतिबंधित करना); unrelated.
· recite: to repeat aloud from memory (Hindi: कंठस्थ सुनाना); not about references.
· facilitate: to make easier (Hindi: सुगम बनाना); too general and not the required action.
