The correct answer is B. apex:dataList.

An apex:dataList component is used to create a list of items that is defined by iterating over a set of data. The data set can include up to 1,000 items. The body of the apex:dataList component specifies how a single item should appear in the list.

For example, suppose you have a list of accounts and you want to display them in a table. You could use an apex:dataList component to iterate over the list and display each account as a row in the table.

Here's an example of how to use the apex:dataList component:

php
<apex:dataList value="{!accounts}" var="acct"> <apex:outputText value="{!acct.Name}"/> </apex:dataList>

In this example, the value attribute of the apex:dataList component is set to {!accounts}, which is the list of accounts that we want to display. The var attribute is set to "acct", which is the variable that we use to refer to each account in the list.

The body of the apex:dataList component contains an apex:outputText component, which specifies how each account should be displayed in the list. In this case, we're displaying the Name field of each account.

So, when the page is rendered, the apex:dataList component will iterate over the list of accounts and display each account's Name field as a separate item in the list.

In conclusion, the apex:dataList component is a powerful tool for displaying lists of data in a customizable way.
