- DOnly (i) and (ii)
Solution
Concept
Dressing gives stones a proper shape and surface. This gives a uniform look, good mortar joints and proper bedding in masonry.
Step-by-step solution
1. Dressing means cutting and shaping the quarried stone to the needed size and surface. 2. Fresh stone has quarry sap, so it is soft and easy to dress before seasoning. 3. Benefits of dressing: uniform appearance (i), good mortar joints (ii) and proper bedding (iii). 4. 'Poor water absorption' is not a purpose of dressing. Water absorption depends on the stone's pores, not on dressing. 5. So (i), (ii) and (iii) are correct. Answer is C.
Explanation
Stones are dressed before seasoning because fresh stone is softer and easy to work. Dressing gives a neat, uniform look and plane surfaces, so the bedding and mortar joints are proper. Water absorption is a property of the stone itself, not a result of dressing.
Why the other options are wrong
A misses mortar joints and bedding. B wrongly includes poor water absorption. D misses proper bedding.
Shortcut
Dressing is about shape and surface (look, joints, bed), not about water absorption.
Common mistake
Thinking a smooth dressed surface reduces water absorption, so selecting all four options.
Correct answer: C) Only (i), (ii) and (iii)
