Each construction task has a specific unit of measurement. This section matches each item to its correct unit.
Step 1: Honeycomb Brickwork is measured in Square Meters, reflecting the calculation of surface area. This corresponds to P–3.
Step 2: Steel Reinforcement is measured in Kilograms because its weight is crucial for material quantity calculations. This corresponds to Q–4.
Step 3: Brick on Edge is counted by the Number of bricks, as individual bricks are considered. This corresponds to R–1.
Step 4: Earthwork in Excavation is measured in Cubic Meters, quantifying the volume of soil removed. This corresponds to S–2.
The correct combination is (D) P–3, Q–4, R–1, S–2.
