With reference to Squinch adopted in dome construction, choose the correct option related to statements P and Q. 
P: Squinch is a structural element used to support the base of a circular or octagonal dome that surmounts a square hall.
Q: Squinch is a double layered dome comprising of an inner and an outer layer of masonry.
 

• A. Both P and Q are true
• B. P is true but Q is false
• C. P is false but Q is true
• D. Both P and Q are false

Hint:

Squinches are typically used in architecture to smoothly transition between square and circular structures, commonly seen in Islamic and Byzantine architecture.

Answer 1

The Correct Option is B

Statement P: A squinch functions as a structural component to reinforce the foundation of a dome, particularly when a circular or octagonal dome is positioned above a square or rectangular chamber. Consequently, Statement P is accurate.
Statement Q: A squinch is not a dual-layered dome; it serves as a transitional support system connecting a square base to a circular or polygonal dome. Thus, Statement Q is inaccurate.
Conclusion: Statement P is true, and Statement Q is false. Option (B) is the correct choice.
