答案是B
这是过去分词的独立主格结构 ,过去分词与逻辑主语是主表关系 。
选项A 是非限制性定语从句 应该是 whose owner was seated ....
选项CD 明显错误 就不说了。
注意 下面 表达 都是对的,注意区别。
1 ,and its owner was seated.....
2, its owner seated.....
3 , whose owner was seated.....
1是并列句2是独立主格结构3是非限制性定语从句
如果动词 是sit 则是
1 ,and its owner sat .....
2, its owner sitting .....
3 , whose owner sat.....
答案是B
是独立主格
独立主格结构在句中做状语

独立主格结构不是句子。
its owner + seated+ in it
B。这题考查独立主格。所谓独立主格就是:名词+非谓语;而定语从句:引导词+主语+谓语+等,从句肯定有真谓语。独立主格只能有非谓语,这是区别。
如果填whose, owner后要加was
