You are given four salt solutions W,X,Y ans X of different concentrations. W is a 20% salt solution, X is a 35% salt solution, Y is a 10% salt solution whereas Z is a 50% salt solution. When a solid suspeded from the hook of a spring balance is fully submerged in all these salt solutions, one by one, then the spring balance will show the minimum reading when the solid is immersed in:

Options

A. solution W
B. solution X
C. solution Y
D. solution Z

Answer

D
