The question asks for the deadline under the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, within which an accused must apply for plea bargaining after charges are formally framed. Checking each proposed timeline against the purpose of that deadline helps confirm the right one.
Among the four options, only the 30-day period matches both the practical need for a workable window and the statutory text governing plea bargaining under the BNSS.
Therefore, the correct answer is 30 days.
