$A$ buffer solution contains $0.1 \ mol$ of sodium acetate in $1000 \ cm^{3}$ of $0.1 \ M$ acetic acid. To the above buffer solution,$0.1 \ mol$ of sodium acetate is further added and dissolved. The $pH$ of the resulting buffer is equal to
- A$pK_{a} - \log 2$
- B$pK_{a}$
- C$pK_{a} + 2$
- D$pK_{a} + \log 2$
