Answer #1

Ans)

b will be the right answer i.e. 9%.

When we plot the moisture content and dry densities on respective axis then we get a curve. IN which the maximum peak point of the soil obtained is called as the Maximum dry density value And The water content correspond to this point is called as the optimum moisture content (O.M.C).
