To solve this problem, we need to use the formula:

moles = mass/molar mass

First, we can calculate the molar mass of NaOH:

molar mass NaOH = 23 + 16 + 1 = 40 g/mol

Next, we can calculate the number of moles of NaOH using the given mass:

moles = 13.5 g / 40 g/mol = 0.3375 mol

Finally, we can use the formula:

Molarity = moles/volume

to solve for the volume of the solution:

0.540 M = 0.3375 mol / volume

volume = 0.3375 mol / 0.540 M = 0.625 L

Therefore, the answer is B.
