Concept:Bulleted and numbered lists arrange related items clearly so readers can see each point separately.
Explanation:Lists are used to organise information into short, manageable lines.
This visual separation helps the reader to identify key facts quickly.
A bulleted list presents items without order, while a numbered list shows a sequence or rank.
Both types reduce long blocks of text, which makes scanning easier.
They also highlight important points because each item stands on its own.
Improved readability is the main benefit in a document.
Using a list does not insert page breaks after every item, so option A is incorrect.
Lists do not automatically change font style or size, so option B is incorrect.
Adding decorative borders and background colours is a formatting feature, not the purpose of a list, therefore option C is incorrect.
Only option D correctly describes the benefit: to highlight important points and improve readability by visually separating items.
Answer:D. To highlight important points and improve readability by visually separating items.
