Klinefelter syndromeis the set of symptoms resulting from additional X genetic material in males. Also known as47,XXYorXXY, Klinefelter syndrome is agenetic disorderin which there is at least one extraX chromosometo a standard human malekaryotype, for a total of 47chromosomesrather than the 46 found in genetically typical humans.

So an extra sex chromosome means an extra barr body. hence option 3 is correct.
