What is a groin vault?

Answer

A groin vault is a structure that resembles the top half of a sphere.

A groin vault comes from the extension of a round arch, similar to a long tube of arches.

A groin vault has two barrel vaults of the same diameter which cross or intersect one another.

A groin vault has two barrels which extrude into a two dimensional structure.

Explanation

A groin vault is formed where two barrel vaults intersect at right angles. Their crossing creates groins, or angled edges, across the vault. So the correct choice is “two barrel vaults of the same diameter which cross or intersect one another.”
