    I believe the correct answer from the choices listed above is option B. The double-displacement reaction would be HNO3 (aq) + KOH (aq) → H2O (l) + KNO3 (aq). It is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places
