Aswer should be zone 4. Zoning start from coarser to finer. So, zone 4 is the finer one. For finer sand surface area is more so more high water cement ratio.

In w/c, Water is In numerator so sand requiring more water will have more w/c ratio.

Yes, right @Sultan.

Zone 1.
It is asked about w/c ratio, not about only water. Zone 1 sands are coarser so they have the comparatively lesser surface area, so they require a lesser amount of cement hence higher w/c ratio.

I think Zone 4 because fine sand having large surface area so w/c ratio will more require to lubricant.

Yeah;
It is zone 4. Because of more surface area.
It is zone 4. Because of more surface area.

Correct answer zone-4, because zone - 4 more surface area compare to zone -1.

I think option a) is correct, because same volume coarse sand required more water.
Garry said:

D is the correct answer.
Bharat said:

Finer sand required more water so Answer D is correct.
