Answer 1

The Correct Option is A

Concept:
Arches, domes, and vaults are important architectural features. They use special structural elements to transfer load and create curved forms.

Step 1: Understand springer.
Springer is the point from which an arch begins to rise. So, A is correct.

Step 2: Understand voussoir.
Voussoirs are wedge-shaped stones used in an arch. So, B is correct.

Step 3: Understand keystone.
The keystone is the central stone at the top of an arch. So, C is correct.

Step 4: Understand centring.
Centring is the temporary wooden framework used during construction of arches or vaults. So, D is correct.

Step 5: Understand drum.
A drum is a circular or polygonal structure supporting a dome. So, E is also correct. Thus, all terms are associated with arch, dome, and vault construction. Hence, the correct answer is: \[ \boxed{\text{(A) A, B, C, D and E}} \]
