Correct Answer:
B. 3 days
The correct answer is 3 days. For a moveable encroachment, a shorter notice period is typically prescribed due to its temporary or easily removable nature. The 3-day notice period allows the Enforcement Officer to address the issue promptly, facilitating quicker resolution and removal of the obstruction. Longer periods such as 7, 15, or 30 days (Options A, C, and D) are generally reserved for more complex, permanent, or immoveable encroachments that require more time for the affected party to respond or comply.
