• B. P-5, Q-3, R-4, S-1
• C. P-2, Q-3, R-5, S-4
• D. P-5, Q-1, R-4, S-3

Hint:

NBC 2016 minimum widths: Habitable room = 2.4 m, Kitchen = 1.8 m, Bathroom = 1.2 m, Stair flight = 1.0 m. Memorize these for quick recall.

Answer 1

The Correct Option is D

Step 1: Minimum width of habitable room.
According to NBC 2016, a habitable room (such as a living room or bedroom) must have a minimum width of 2.4 m. \[ P \Rightarrow 5 \]

Step 2: Minimum width of stair flight.
The NBC specifies that a stair flight in residential buildings should not be less than 1.0 m wide to allow safe passage. \[ Q \Rightarrow 1 \]

Step 3: Minimum width of kitchen.
For kitchens, NBC requires a minimum width of 1.8 m, so that circulation and platform space are adequate. \[ R \Rightarrow 4 \]

Step 4: Minimum width of bathroom.
Bathrooms require a minimum width of 1.2 m for usability. \[ S \Rightarrow 3 \]

Step 5: Final matching.
Thus, the correct sequence is: \[ P-5, \; Q-1, \; R-4, \; S-3 \] This matches with Option (D).

Final Answer: \[ \boxed{\text{(D) P-5, Q-1, R-4, S-3}} \]
