Fill in the blank with an appropriate preposition in the following sentence.

The boy fell _______ the roof.

off

The correct answer is Option (2) - off

• "Off" is the correct preposition to use when indicating that someone or something has moved downward from a higher position, such as falling from a roof.

• "Under": Incorrect, as it suggests being below something, not falling from it.
• "Of": Incorrect, as it does not indicate movement or direction.
• "Since": Incorrect, as it is used for time or cause, not spatial movement.
