Explanation:

The 4th edition of the Khelo India Youth Games was originally scheduled for 2021 but was postponed to February 2022 due to the COVID-19 pandemic. The state chosen to host these games was **Haryana**. The events were primarily held in Panchkula, with some events in Chandigarh, Ambala, Shahabad, and Delhi. Option (A) Punjab, Option (C) Gujarat, and Option (D) Karnataka have hosted or are slated to host other major sporting events or editions of the Khelo India Games, but Haryana was the host for the February 2022 edition. For instance, the 2023 Khelo India Youth Games were held in Madhya Pradesh, and the 2024 edition in Tamil Nadu. Thus, Haryana is the correct host for the February 2022 games.
