First, we need to calculate the number of moles of HF in the solution:
n(HF) = m(HF) / MM(HF) = 16.4 g / 20.01 g/mol = 0.819 moles HF

Next, we need to calculate the volume of the solution in liters:
V = 2.0 x 10^-10 m^3 x (1 L / 1000 cm^3) = 2.0 x 10^-13 L

Finally, we can calculate the concentration of the solution:
C = n(HF) / V = 0.819 moles / 2.0 x 10^-13 L = 4.1 M

Therefore, the correct answer is D.
