Final answer:
The title 'Of Mice And Men' should capitalize 'And' to be correct according to MLA style and it should also be italicized, making the correct format 'Of Mice and Men.'
Step-by-step explanation:
The title “Of Mice And Men” is not capitalized correctly according to MLA style. In titles, the first word, all principal words, and all words longer than three letters should be capitalized. Therefore, the correct capitalization is “Of Mice and Men.” When referencing the title in a work, it should also be italicized as it is the title of a book, which is considered a long work.
