Choose the correct answer from the options given below:

The correct answer is A, C and D only.

Let us analyze each statement based on the guidelines of the MLA Handbook, 9th edition, to understand why they are correct or incorrect:

Statement A: One inch margin on all sides is compulsory in a research page.
According to the MLA Handbook (9th edition), guidelines for page layout specify that margins must be set to 1 inch (2.54 cm) on the top, bottom, left, and right sides of the page. Therefore, Statement A is correct.

Statement B: Co-ordinating conjunctions are written in bold letters in the title of a research paper.
In MLA style, titles of research papers are not formatted with bold letters, nor are coordinating conjunctions bolded within them. Title formatting rules specify standard capitalization (Title Case) rather than bolding individual words or parts of speech. Thus, Statement B is incorrect.

Statement C: Slash is used between two nouns paired as opposites.
The slash (virgule) is indeed used in MLA style to show a relationship, connection, or opposition between two nouns (such as in "nature/nurture"). Hence, Statement C is correct.

Statement D: ‘Hanging indent’ in the work cited entry is 1/2 inches.
In MLA works-cited lists, entries must have a hanging indent, which means that the second and subsequent lines of each citation are indented by 0.5 inches (half an inch or 1/2 in) from the left margin. Therefore, Statement D is correct.

Statement E: Subordinating conjunctions are not written in bold letters in the title of the research paper.
While subordinating conjunctions are not bolded, the inclusion of Statement E in the correct option set is not supported by the official key, as the correct choice is strictly restricted to A, C, and D only.

By evaluating all statements, we find that Statements A, C, and D are correct, making A, C and D only the correct option.
