[tlhIngan Hol] SoHvaD yuchwIj vIbonqangbe'

Suppose I see a Klingon enjoying some chocolate and ask, “jIHvaD yuchlIj Dabonqang'a'?” Assume that the Klingon wishes to keep all of the chocolate for him or herself (as suggested by the subject of this message). Would the most appropriate one-word response be “ghobe'” (because the question was asked with -'a'), “Qo'” (because it’s a question about volition), or is either fine?
