this is NaCl and HCl, because of the fact there is not any way that they could be mixed to variety the two a susceptible acid/conjugate base or susceptible base/conjugate acid pair. consistent with the previous respond, RbOH and HF can variety a buffer. If there is extra HF than RbOH, then the hydroxides will pull the H+ of each and every of the HF it may, forming water and F-. the the remainder of the HF will stay linked. for that reason, you have HF (a susceptible acid) and F- (a conjugate base) in answer.

D. as a weak acid and weak base pair is present, Nh3 a weak base and Nh4+ a weak acid
This can be prove as the formula by the following equation for ph
ph= pka + log([weak base]/[weak acid]

none of these...
they are the pair of Strong Base n its salt with weak acid...or other way round that is Strong Acid and its salt with weak base.....
