Option 1 -> Places Snow Marathon first (January 2023), but 5G was launched earlier in October 2022.
Option 2 -> Correctly sequences: 5G launch (Oct 2022), Snow Marathon (Jan 2023), Buddhist Summit (April 2023), Garba UNESCO recognition (Dec 2023).
Option 3 -> Places Garba recognition (Dec 2023) before Buddhist Summit (April 2023), which is incorrect.
Option 4 -> Starts with Garba (Dec 2023) as the first event, which is chronologically wrong.
Hence, Option 2: (B), (A), (D), (C) -> 5G services were launched in October 2022, followed by the Snow Marathon in Jammu in January 2023, the First Global Buddhist Summit in April 2023, and finally UNESCO's declaration of Garba as intangible Cultural Heritage in December 2023 -> correct
