The correct answer to this question is B. apex:iframe.
The apex:iframe component allows you to embed a web page or another Visualforce page within your Visualforce page. It creates an inline frame, which is a rectangular area within a web page that displays the content of another web page.
Using an iframe can be useful if you want to display information from another website or if you want to display information from another page within your own Visualforce page. You can set the height and width of the iframe using attributes, and you can also set the source of the iframe to be dynamic by using an expression that returns a URL.
For example, the following code creates an iframe that displays the Google homepage:
php<apex:iframe src="https://www.google.com" height="500" width="800"/> This code creates an iframe that is 500 pixels high and 800 pixels wide and displays the Google homepage. You can also set the source dynamically using an expression. For example:
php<apex:iframe src="{!myUrl}" height="500" width="800"/> In this example, myUrl is a controller variable that returns a URL, and the iframe displays the content of that URL.
The other answer choices are:
A. apex:include: This component allows you to include the content of another Visualforce page within your own page. It is similar to apex:iframe, but instead of embedding another website or web page, it embeds another Visualforce page.
C. apex:chartLabel: This component is used to create labels for chart data points in a Visualforce chart. It is not related to inline frames.
D. apex:attribute: This component is used to define attributes for a Visualforce component. It is not related to inline frames.
