【C017179】使用MyBatis时，有如下代码：

<select id="findActiveBlogWithTitleLike"

parameterType="Blog" resultType="Blog">

SELECT * FROM BLOG

WHERE state = 'ACTIVE'

___________

AND title like 'MyBatis'

</if>

</select>

这段配置文件需要判断“title”字段是否为空，则可以填写在横线处的代码是(  )

• A.<if test="title" != null>

• B.<if test="title != null">

• C.<if title != null>

• D.<if title ="test != null">
