Step 1: Read the question.
Under the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, an accused who wants to apply for plea bargaining must do so within a fixed number of days after charges are framed. We must find that number.
Step 2: Understand plea bargaining.
Plea bargaining is a process where the accused agrees to plead guilty in return for a benefit, such as a lighter sentence. It helps settle cases faster and reduces the load on courts.
Step 3: Know why a time limit exists.
The law wants this choice to be made early, soon after the accused learns the exact charges against him. An early decision keeps the trial moving and stops the option from being misused to cause delay.
Step 4: Find the prescribed period.
The BNSS requires the accused to file the plea bargaining application within 15 days from the date the charges are formally framed by the court.
Step 5: Check the wrong options.
Option (A), 7 days, is shorter than the period given by the BNSS. Option (C), 30 days, is longer than allowed. Option (D), 60 days, is not contemplated by the plea bargaining provisions.
Step 6: Conclude.
So the correct period is 15 days from the framing of charges.
\[ \boxed{\text{15 days}} \]
