First, we need to find the mass of ammonium chloride in the solution. Let's assume we have 100 g of the solution. Therefore, the mass of ammonium chloride in the solution is:

24.0 g/100 g x 100 g = 24.0 g

Next, we can use the density of the solution to find its volume:

density = mass/volume

11ea6923_182b_3d5d_80d0_255321e865cf_TB6105_11 = 100 g/volume

volume = 100 g/11ea6923_182b_3d5d_80d0_255321e865cf_TB6105_11 = 9.09 mL

Now we can find the molarity of ammonium chloride in the solution:

mass = molarity x volume x formula weight

24.0 g = molarity x 9.09 mL x 53.50 g/mol

molarity = 4.79 mol/L

Therefore, the answer is C) 4.79.
