# Brief Explanations:
In arch - architecture, the keystone is the central and crucial stone at the apex of an arch that locks the other stones in place. In the given diagram, part (A) is the keystone. The impost is the top part of the pier or wall on which an arch rests (usually labeled as the green - colored part in the diagram). The springing line is the horizontal line at the level from which an arch springs. Voussoirs are the wedge - shaped stones that make up the arch other than the keystone.
