Answer 1

Answer:

I think it's answer is c. A groin vault has two barrel vaults of the same diameter which cross or intersect one another.

Explanation:

A groin vault or groined vault (also sometimes known as a double barrel vault or cross vault) is produced by the intersection at right angles of two barrel vaults. The word "groin" refers to the edge between the intersecting vaults. Sometimes the arches of groin vaults are pointed instead of round.

Answer 2

Answer: What is a groin vault? C. A groin vault has two-barrel vaults of the same diameter which cross or intersect one another.

A is wrong because it doesn't resemble the top half of a sphere.

B is wrong because it does not come from an extension of round arches.

D is wrong because it does not extrude into a two-dimensional structure.
