We are asked which of the following options would yield 0.200 M K2SO4 solution

When we are adding water (or solvent) to a solution to decrease its concentration, we are diluting the solution.

When dealing with dilution we will use the following equation:

$\overline{){{\mathbf{M}}}_{{\mathbf{1}}}{{\mathbf{V}}}_{{\mathbf{1}}}{\mathbf{=}}{{\mathbf{M}}}_{{\mathbf{2}}}{{\mathbf{V}}}_{{\mathbf{2}}}}$

M1 = initial concentration
V1 = initial volume
M2 = final concentration
V2 = final volume
