This question was addressed to me by my school teacher while I was bunking the class.

I'd like to ask this question from Definition of Technical Terms topic in section Doors, Windows and Ventilators of Construction & Building Materials

Answer 1

Right choice is (c) Holdfasts

For explanation I would say: Holdfasts are used to fix the frame in the opening of the wall. These are mild steel bars and their proper painting must be ensured before fixing them.
