To calculate the [OH-], we first need to find the [H+]. The pH is given by pH = -log[H+], so we can rearrange to find [H+].

pH = 5.330 = -log[H+]
log[H+] = -5.330
[H+] = 10^-5.330

Now we can use the fact that Kw = [H+][OH-] to find [OH-].

Kw = 1.0 x 10^-14
[H+] = 10^-5.330

[OH-] = Kw/[H+] = (1.0 x 10^-14)/(10^-5.330) 
[OH-] = 2.14 x 10^-10 mol/L

So the answer is A, which gives the [OH-] in molar units.
