Yess I have the same doubt.. it should be y linked only

consider the case when the parent female and all the 1 St generation females are carrier.....
It will show x-linked recessive trait...

yes it is y linked only 
* if the daughters are carriers then the representation of carrier will shown as circle half shaded 
* x linked recessive is occurs in alternate generations but it is not given in the chart
*if it is x linked recessive  progeny half of the progeny will be affected....but it does not follow in the given chart
So, that answer must be Y LINKED ONLY
