I would say d is the answer.
a) pH would  be pKs, its not pH7, use Henderson Hasselbalch equation
b) similar to a) still acidic
c) HNO3 is strong acid, very acidic

You need to check the nature of the solution after mixing the components of the mixture.
a) It is a basic buffer - pH >7
b) acidic buffer -pH <7
c) Neutral salt with strong acid ---pH <<< 7
d) weak base and weak acid reacts to give a salt of weak acid and weak base.
pH is nearly 7
