Which of the following pairs contains a conjugate acid-base pair?
Hydrochloric acid and sodium hydroxide
Sodium cyanide and hydrocyanic acid
sodium bromide and bromous acid

Verified Answer :

TSO

Remember that a conjugate acid-base pair will differ only by one proton. 
None of the options you listed are conjugate acid-base pairs as none of them differ only by one proton (or H⁺)
An example of a conjugate acid-base pair would be NH₃ and NH₄⁺NH₃ + H₂O --> NH₄⁺ + OH⁻NH3 is the base, and NH₄⁺ is the conjugate acid
