You create a Microsoft ASP.NETWeb application by using the Microsoft .NET Framework
version 3.5.The application contains the following device filter element in the Web.config
file.
<filter name=”isHtml” compare=”PreferredRenderingType” argument=”html32″ />
The application contains a Web page that has the following image control. (Line numbers are
included for reference only.)
01 <mobile:Image ID=”imgCtrl” Runat=”server”>
02
03 </mobile:Image>
You need to ensure that the following conditions are met:
The imgCtrl Image control displays the highRes.jpg file if the Web browser supports
html.
The imgCtrl Image control displays lowRes.gif if the Web browser does not support
html.
Which DeviceSpecific element should you insert at line 02?

A.
<DeviceSpecific>
<Choice Filter=”isHtml” ImageUrl=”highRes.jpg” />
<Choice ImageUrl=”lowRes.gif” />
</DeviceSpecific>

B.
<DeviceSpecific>
<Choice Filter=”isHtml” Argument=”false” ImageUrl=”highRes.jpg” />
<Choice Filter=”isHtml” Argument=”true” ImageUrl=”lowRes.gif” />
</DeviceSpecific>

<DeviceSpecific>
<Choice Filter=”PreferredRenderingType” ImageUrl=”highRes.jpg” />
<Choice ImageUrl=”lowRes.gif” />

<Choice Filter=”PreferredRenderingType” Argument=”false” ImageUrl=”highRes.jpg” />
