本题考查HTML页面链入外部CSS文件的用法。
链入外部CSS文件应在HTML页面head区域添加如下格式代码：
＜link type=“text/css”rel=“stylesheet”href=“css所在路径”/>
根据题意，样式表文件名为mystyle.css
故表示为＜link type=“text/css”rel=“stylesheet”href=“mystyle.css”/>，本题选B（其中ABC项表示错误）
插入CSS3四种方式
（1）内嵌样式表：直接添加在html的标识符里
例如：＜p style=“color:black;font-size:14px;”>CSS实例＜/p>
（2）内部样式表：定义在＜head>＜/head>间，仅作用于本文档
例如：＜style type="text/css">
body{color:blue;font-size:20px;}＜/style>
（3）链入外部样式表：CSS以文件的形式存在，在＜head>＜/head>间使用＜link>标记连接外部文件
例如：＜link rel=“stylesheet”type=“text/css”href=“xxx.css”>＜/link>
（4）导入外部样式表：直接导入外部CSS文件
例如：＜style type=“text/css”>
@import url（外部样式表文件地址）；＜/style>
