Match the specially shaped bricks in Group-I with their corresponding nomenclature in Group–II. Group-I Group-II (P) 
(1) Plinth Header (Q) 
(2) Bird's mouth (R) 
(3) Squint (S) 
(4) Double cant (5) Plinth stretcher
The problem requires matching specially shaped bricks in Group-I with their corresponding nomenclature in Group-II. Let's go through each option to determine the correct matches:




Based on the analysis above, the correct match would be:
Hence, the correct option is: P – 4, Q – 3, R – 5, S – 1
By correctly identifying the shapes and functionality of each brick type, we ensure compatible usage in construction which is crucial for structural integrity and aesthetic considerations.
