How coarse aggregates surface area is less?
Fine aggregates surface area is less.
Least surface area required more water.
Fine aggregates surface area is less.
Least surface area required more water.

The Given answer is correct.
It says "least amount of water which gives greatest surface area for given amount of cement and aggregates.
It says "least amount of water which gives greatest surface area for given amount of cement and aggregates.

Given Answer is correct because finely grinded cement required less water and it cover more area.

For a given workability means it is fixed.
If we want same amount of easyness with that concrete paste then surface area should be low.
As we will increase fineness more area will absorb water and friction increases so can't give the same level of easyness means workability.

@Sanam.
It Means as grade increase water required for greater surface area decreases.
