Which of these is a typographical clue?

a. a definition

b. a contrast

c. an italicized word

d. a cause and effect

Typography has been defined as a technique to make written text readable and appealing. It involves typefaces, line-spacing, highlighting (bold-facing, italicizing, underlining), line-length, and such. Definition has nothing to do with typography since it deals with statement that give meaning to certain words. So as contrast, which gives the exact opposite of something. Lastly, cause and effect is a technique of showing reasons in relation to what had happened. Therefore, the typographical clue is an italicized word, which highlights important details in a text.
