Correct Answer:
B. 15 days
The correct answer is 15 days. For an immoveable encroachment, the Hearing Officer typically provides a reasonable but firm timeframe for the illegal occupier to vacate. 15 days strikes a balance, allowing sufficient time for the occupier to make arrangements for removal or relocation, while also ensuring timely enforcement against illegal occupation. A 3-day period (Option A) would likely be too short for an immoveable structure, whereas 30 or 60 days (Options C and D) might be considered excessively long, potentially delaying necessary action and prolonging the illegal occupation.
