None of them. The name is a proper noun, so use capital initial letters as for example Anytown University or Somewhere College. Similarly with endowed, foundation, military or church establishments. Underlining and italicising is usually used for scientific terms, especially in Biology. Quotes are better used in work intended for a general readership, where you may need to use a technical term but follow that by its definition.
Italicize or underline the title.
YES!
You would underline or italicize the name of the book on tape rather than use quotation marks.
No just underline
No, you do not need to underline the name of a seminar listed on an agenda. Simply bold or italicize it to make it stand out.
No, you would italicize the name "Netflix" when writing it in a formal document or publication.
No, you would italicize or underline the name of a painting. If you are using MLA format, then you should underline the name. The way I remember is that quotations go around short works like poems or plays, whereas sculptures and paintings take a long time to create. (Debatable, yes, but it's a helpful mnemonic.)
No, it is not necessary to underline a scientific name even if it is completely written in capital letters. The proper format for writing a scientific name is to italicize it or underline it to indicate that it is a Latinized binomial name.
Italicizing and underlining accomplish the same thing; either is technically correct. However, if the drama name is typed, it is best to italicize it. When written out by hand (making it nearly impossible to italicize), underlining is acceptable instead.
No, the name of a magazine is in Itallics if typed, and in quotes if handwritten.
No you do not
No if you're typing the name you italicize it but if you're writing it on a piece of paper you underline it.
