Which of the following is a guideline for creating effective links in online documents?

A) Trust readers to know what the linked page will contain.
B) Structure your sentences as if there were no links in the text.
C) Use custom colors for linked text.
D) Make links bold, italic, and underlined for emphasis.

Structuring sentences as if there were no links allows the text to flow naturally and ensures that the links are not obtrusive. Trusting readers to know what the linked page will contain may lead to confusion or frustration if the linked page does not match their expectations. Using custom colors for linked text or making links overly emphasized can be distracting and disrupt the overall reading experience.
