I had been asked this question in an interview for job.

My question comes from Parts of Window in chapter Doors, Windows and Ventilators of Construction & Building Materials

The correct option is D. Flush

For explanation I would say: There are two varieties of flush doors i.e. frame flush door and a laminated flush door. A framed flush door consists of styles, rails, horizontal ribs, vertical ribs and plywood. A laminated flush door consists of styles, rails, laminated core and plywood.
