Section 173 of the BNSS, 2023 is drafted to stop a complaint from being silently shelved, and it fixes a precise number of days for the officer-in-charge to tell the informant if the case will not be investigated because it lacks sufficient gravity. Testing the given options against that number resolves the question directly.
Since none of the other periods correspond to the statutory language of Section 173 while fourteen days matches it exactly, that is the operative timeline.
Two timelines in criminal procedure are frequently mixed up: the twenty-four hour rule for producing an arrested person before a magistrate, and the notice period under Section 173 of the BNSS for telling a complainant that their case will not be investigated. Distinguishing these two makes the answer clear.
Once the twenty-four hour custody rule is set aside as addressing a different situation altogether, and the seven and thirty day options are excluded as not matching the statutory text, the fourteen-day period specified in Section 173 remains the correct timeline.
Therefore, the correct answer is 14 days.
