(A) The correct statements are:
$i$. True (It is used to separate glycerol from spent lye in the soap industry).
$ii$. False (Vacuum pumps are used,but air pumps are generally not used for this purpose).
$iii$. True (Distillation at reduced pressure prevents the decomposition of heat-sensitive substances).
$iv$. False (The process is specifically designed to prevent decomposition).
$v$. True (Reducing the pressure lowers the boiling point of the liquid).
Summary: $i-T, ii-F, iii-T, iv-F, v-T$.
