Best answer
if both end points of a line is at either one end i.e ( both are left,right,above and below )then clearly they are not visible or invisible (so choice B, C are out ) now since nothing has to be done to them neither clipping nor reatining so we ignore them  completely or they are trivial for us hence the line is trivially invisible

so ans is D
