We can use the formula:

Mass % = (mass of solute / mass of solution) x 100%

First, let's calculate the mass of the solution:

mass of solution = density x volume
mass of solution = 1.06 g/mL x 875 mL
mass of solution = 927.5 g

Next, we can use the given information to calculate the mass of NaCl:

mass of NaCl = 98.6 g

Finally, we can plug these values into the formula:

Mass % = (mass of NaCl / mass of solution) x 100%
Mass % = (98.6 g / 927.5 g) x 100%
Mass % = 10.6%

Therefore, the answer is D (10.6%).
