Question

Match List - I with List - II 

List - I (Material)	List - II (Applied as)
A. Enamel	IV. Paint
B. Mineral wool blanket	III. Insulating material
C. Mastic Asphalt	I. D.P.C
D. UPVC	II. Window frames

• A. A-IV, B-II, C-III, D-I
• B. A-II, B-III, C-IV, D-I
• C. A-IV, B-III, C-I, D-II
• D. A-IV, B-I, C-III, D-II

Hint:

Important material applications:
• Enamel $\rightarrow$ Paint finish
• Mineral Wool $\rightarrow$ Thermal insulation
• Mastic Asphalt $\rightarrow$ Waterproofing D.P.C
• UPVC $\rightarrow$ Window and door frames

Answer 1

The Correct Option is C

Concept: Different construction materials are used for specific purposes in buildings depending on their physical and functional properties such as durability, insulation, waterproofing, and finish quality.

Step 1: Match each material with its application.
• A. Enamel
Enamel is a type of paint used for durable and glossy surface finishes.
Therefore: \[ A \rightarrow IV \]
• B. Mineral wool blanket
Mineral wool is widely used as a thermal and acoustic insulating material.
Therefore: \[ B \rightarrow III \]
• C. Mastic Asphalt
Mastic asphalt is commonly used as Damp Proof Course (D.P.C.) because of its waterproofing properties.
Therefore: \[ C \rightarrow I \]
• D. UPVC
UPVC (Unplasticized Polyvinyl Chloride) is commonly used for doors and window frames.
Therefore: \[ D \rightarrow II \]

Step 2: Identify the correct combination.
Thus, the correct matching is: \[ A-IV,\; B-III,\; C-I,\; D-II \] Therefore, the correct answer is: \[ {A\text{-}IV,\; B\text{-}III,\; C\text{-}I,\; D\text{-}II} \]
