\(A.\) the polarity increasing in the order is \(HI\, <\, HBr\, < \,HCl\, <\, HF\)

, as suggested by the electronegativity differences. \(H - F\) is more polar than \(HBr\), therefore option \(A\) is wrong as it say \(HF\) is less polar than \(HBr\).

\(B.\) Absolutely pure water does not contain any ions is false because pure water, has an amphiprotic nature. This means that a small amount of ions will form in pure water.

\(C.\) Chemical bond formation take place when force of attraction overcome the forces of repulsion is true because the bond is result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.

\(D.\) In co-valency transference of electron takes place is wrong because he formation of an Ionic bond is the result of the transfer of one or more electrons from a metal onto a non-metal.
