The question was posed to me during an online interview.

This key question is from Parts of Window topic in chapter Doors, Windows and Ventilators of Construction & Building Materials

Answer 1

Correct answer is (a) Ledged

The best I can explain: In Ledged doors, the battens are 100 mm to 150 mm wide and 20 mm to 30 mm thick. The ledges are generally 100 mm to 200 mm wide and 30 mm thick. The three ledges are generally employed to top, middle and bottom. The battens are secured by means of suitable joints and the shutter is hung on T-Hinges which are fixed on the ledges.
