D: Raised ceruloplasmin level
Answer: D: Raised ceruloplasmin level 
Explanation: Low levels of ceruloplasmin are characteristic.This is probably secondary to hepatic damage. As most of the copper in serum is bound to ceruloplasmin, total serum copper level is reduced.The serum ceruloplasmin level is less than 20mg/dl and serum copper concentration is below 20 micrograms/dl.
