A requisition from an Enforcement Station under Section 20 of the Act must be forwarded by the HO to the Board within:

The correct answer is 3 days of receipt. According to Section 20 of the Act, a requisition received from an Enforcement Station must be forwarded by the Hearing Officer (HO) to the Board within three days of its receipt. This specific timeframe is mandated to ensure the prompt and efficient processing of such requisitions, maintaining the operational flow and legal compliance. Other options like 24 hours, 7 days, or 15 days are incorrect as they do not align with the precise legal requirement stipulated in the Act.
