First, we need to convert the mass of HCl to moles:

25.5 g HCl x (1 mol HCl/36.46 g HCl) = 0.6998 mol HCl

Next, we calculate the total volume of the solution:

11.7 L water (given) + 0 L HCl = 11.7 L total solution

Now we can calculate the molarity (M) of the HCl solution:

M = mol/L 
M = 0.6998 mol / 11.7 L 
M = 0.0350 M

Therefore, the answer is B) 0.0350.
