Which statement is correct for the given reactions?

Consider the above reaction,the major product $P$ formed is:

To which of the following four types does this reaction belong: $B^{-} + R - A \to B - R + A^{-}$?

State True or False for the following statements:
$(i)$ Positive and negative ions are formed by homolytic cleavage of a covalent bond.
$(ii)$ Positive and negative ions are formed by heterolytic cleavage of a covalent bond.
$(iii)$ Only homolytic cleavage is possible in the $C-Cl$ bond of $CH_3-Cl$.
$(iv)$ If heterolytic cleavage of a bond occurs,then ionic or polar type reactions take place.

The product $(A)$ is:

Match Column-$I$ and Column-$II$ with the correct relation:

Column-$I$	Column-$II$
$(i)$ Substitution reaction	$(p)$ $CH_2=CH_2 + Br_2 \to CH_2Br-CH_2Br$
$(ii)$ Addition reaction	$(q)$ $C_6H_6 + NO_2^+ \to C_6H_5NO_2 + H^+$
$(iii)$ Electrophilic addition reaction	$(r)$ $CH_3Cl + NaOH \to CH_3OH + NaCl$
$(iv)$ Electrophilic substitution reaction	$(s)$ $CH_3CH_2OH \xrightarrow[\Delta]{Al_2O_3} CH_2=CH_2$
$(v)$ Elimination reaction
