I had been asked this question in an interview.

Asked question is from Sizes and Dimensions of Various Works in MKS and FPS topic in chapter Nomography, Computer Aided Drafting & Procedure of Estimating of Civil Engineering Drawing

Answer 1

Correct choice is (b) per no.

For explanation I would say: A door is a solid barrier i.e. fixed in the opening of a wall. It can be opened for access to and from buildings and between the rooms or closed for privacy. The door has two parts: one part is frame and second part is shutters.

   A window is an opening in a wall, door, roof or vehicle that allows the passage of light, sound, and air. Modern windows are usually glazed or covered in some other transparent or translucent material, a sash set in a frame in the opening; the sash and frame are also referred to as a window. Many glazed windows may be opened, to allow ventilation, or closed, to exclude inclement weather. Windows often have a latch or similar mechanism to lock the window shut or to hold it open by various amounts.
