Architectural Elements Matching Solution

This question requires matching elements from Group I with their corresponding applications in Group II. Let's analyze each element:

• P - Bracket: Brackets are often employed to support projecting elements. In architecture, they are frequently used to hold or support a Cornice. Thus, P matches with 3.
• Q - Baluster: Balusters are vertical pillars that support a railing or coping. They are a key component of Staircase railings and other elevated walkways. Thus, Q matches with 5.
• R - Keystone: The Keystone is the central stone or wedge-shaped piece at the apex of an arch, essential for its structural integrity. Thus, R matches with 4.
• S - Holdfast: A Holdfast is a metal fixture used to secure or attach one part to another, commonly used in construction to fix elements like door frames or timber to masonry. Thus, S matches with 1.

Final Matching

Based on the analysis, the correct pairings are:

• P - 3 (Bracket - Cornice)
• Q - 5 (Baluster - Staircase)
• R - 4 (Keystone - Arch)
• S - 1 (Holdfast - Door)

Therefore, the correct option is P-3, Q-5, R-4, S-1.
