Separating when the BNSS was enacted from when the BNSS actually took effect is the key to this question, since the two are different dates and only the second one is what the question asks for.
Since the question asks for the commencement date rather than the assent date, and only July 1, 2024 corresponds to the Government's notification bringing the BNSS into force, that is the correct answer.
The key legal distinction this question tests is the difference between when a statute receives Presidential assent and when it is actually brought into force, and comparing these two milestones directly against the four dates resolves the answer.
Because the question specifically asks about coming into force rather than the date of assent, and the Government's own notification identifies 1 July 2024 as that date, this is the option that answers the question correctly.
Therefore, the correct answer is July 1, 2024.
