Which of the following pairs would make a good buffer solution in an aqueous solution?

A) H2SO4 and NaHSO4
B) Ca(NO3)2 and HNO3
C) HCl and NaCl
D) HF and NaOH
E) none of them

I know the answer is D but I don't understand why. I would think it would be C since a goo buffer is a weak acid and it's salt.
