The correct option is C poor (line 32392)
Lacy is ' much affected' to Rose; Lacy is the biggest 'unthrift' in the world; Lacy is of 'high' birth and the Earl refers to Lacy as his 'jolly' cousin. As we can see, all of the given choices apart from option C have been used in reference to Lacy. Lacy has never been referred to as 'poor' in the given passage. So, C is the answer.
