The numeral in the days given for an immovable encroachment removal order is:

The question pertains to the standard timeframe for compliance with an order to remove an immovable encroachment. 15 days is the correct answer because it represents a commonly stipulated period in administrative and legal frameworks, providing a reasonable window for the affected party to take action without undue haste or prolonged delay.

• Option A (3 days) and Option B (7 days) are typically too short for the removal of an immovable structure, which often requires significant effort and resources.
• Option D (30 days), while seemingly generous, might be considered too long, potentially delaying necessary enforcement actions against encroachments and hindering public interest.

Thus, 15 days strikes a balance between fairness to the encroacher and the need for timely resolution.
