The mass of a single DNA molecule can be calculated using Avogadro's number (6.022 x 10^23 mol^-1) and the molar mass given. The calculation is as follows: (1 mol / 6.022 x 10^23 molecules) * (10^19 g/mol) = 1.66 x 10^-5 g/molecule = 1.66 x 10^-2 ng/molecule, which is approximately 1.7 x 10^-6 ng, matching choice C.
