First we need to calculate the mass of the solution:

mass of solution = density x volume = 1.06 g/mL x 875 mL = 926.5 g

Then we can calculate the mass of the NaCl:

mass of NaCl = 98.6 g

Finally, we can calculate the mass percent of the solution:

mass percent = (mass of NaCl / mass of solution) x 100%
mass percent = (98.6 g / 926.5 g) x 100% = 10.6%

Therefore, the correct answer is D) 10.6%.
