Which of the following statements are correct?
(i) The extent of dissociation of an acid depends on the strength and polarity of the \( \mathrm{H}-\mathrm{A} \) bond (where \( \mathrm{A} \) is an electronegative element.)
(ii) As the strength of \( \mathrm{H}-\mathrm{A} \) bond increases, the energy required to break the bond decreases.
(iii) As the electronegativity difference between the atoms \( \mathrm{H} \) and \( \mathrm{A} \) increases, acidity increases
(a) (i) and (ii)
(b) (ii) and (iii)
(c) (i) and (iii)
(d) (i), (ii) and (iii)
