Benzyl halides undergo nuclephilic substitution reaction easily while Phenyl halide does not. For Phenyl halide to give the reaction, high temperature and pressure conditions are required (623 K , 300 atm).
Thus, the benzyl halide undergoes substitution with forming a Benzyl alcohol while the Iodide ion comes into the solution in the form of
which gives a yellow precipitate upon addition of
Hence, the correct answer is Option (1)
