Correct answer: B. H _ 2 N - ( CH _ 2 ) _ 4 - NH _ 2

Substituted ammonium salt is formed when chloroalkane reacted with excess of ${NH}_{3}$ , which on reaction with $NaOH$ gives $1, 4 - diaminobutane$ .

The carbon - halogen bond in alkyl halides can be easily cleaved by a nucleophile. Hence, an alkyl halide on reaction with an ethanolic solution of ammonia undergoes a nucleophilic substitution reaction in which the halogen atom is replaced by an amino group. This process of cleavage of the $C – X$ bond by ammonia molecule is known as ammonolysis. Substituted ammonium salt on reaction with sodium hydroxide gives 1,4-diaminobutane as shown below,
