Answer: The pair that consists of a base and its conjugate acid in that order.
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.



 
 
 is gaining a proton, thus it is considered as a brønsted-lowry base and after gaining a proton, it forms
  is gaining a proton, thus it is considered as a brønsted-lowry base and after gaining a proton, it forms which is a conjugate acid.
  which is a conjugate acid.
