Answer 1

The correct answer is (d) per sq m

The explanation: On a door frame, the sill is the portion of the door frame that runs along the bottom and sits directly on the foundation of your floor. It is the cross piece that actually completes the pre-installed door frame. The sill is actually underneath your threshold.
