In standard formatting, the following items should be italicized:
A. The television series titled Adventures of Rin Tin Tin
B. A short story titled An Ode to Rin Tin Tin
C. Rin Tin Tin (this may depend on context; if referring to the character or name of a work, italics are appropriate)
D. An article in a newspaper titled Who is Rin Tin Tin
So, the italicized items would be:
- Adventures of Rin Tin Tin
- An Ode to Rin Tin Tin
- Rin Tin Tin (if referring to the character's name in certain contexts)
- Who is Rin Tin Tin
In general, titles of television shows, books, films, and similar works are italicized, while the titles of articles, short stories, or poems are typically put in quotation marks or italicized depending on the style guide being followed. In this case, the provided formatting seems to suggest italicizing all titles.
