HI and I⁻ is the acid-conjugate base pair.
<h3>What is acid and conjugate base pair?</h3>
According to Bronsted-Lowry definition of acid and base, those pair which are differ in the single no. of proton or H⁺ ion is known as acid and conjugate base pair or base and conjugate acid pair.
Given chemical reaction is:
HI + H₂O → H₃O⁺ + I⁻
Here, HI = acid,
H₂O = base,
H₃O⁺ = conjugate acid and
I⁻ = conjugate base
Hence, option (d) is correct i.e. HI & I⁻ is the acid-conjugate base pair.

Answer:
Explanation:
Combination Reaction: is a reaction that occurs when two or more reactants combine to form a single new products. The reactants can either be Elements or Compounds. It does not require heat during the reaction.
A + B ---------> C
C (s) + O2 (g) ----------> CO2 (g)
CaO (s) + H2O (l) ---------> Ca(OH)2 (s)
In this reaction, energy is released.
Decomposition Reaction: is a reaction that occurs when a a single reactant is broken down to form two or more products. Application of heat is usually required in this type of reaction.
Δ
AB ---------> C + D
Δ
CaCO3 (s) --------> CaO (s) + CO2 (g)
In this reaction, energy is absorbed.
