Final Answer:
The roof needs repairing in a few places. Option B is the answer.
Step-by-step explanation:
The terms "fixing," "repairing," and "mending" are often used interchangeably, but in the context of a roof, the most appropriate choice is "repairing." When we say "the roof needs repairing," it implies addressing specific issues or damages to restore the roof's functionality and structural integrity.
"Fixing" is a general term that could apply to various improvements, while "mending" might be associated with more minor repairs or sewing. However, when discussing a roof, which is a critical component of a building's structure, "repairing" is a suitable term indicating a more comprehensive and necessary restoration process to address specific issues or damages.
Option B is the answer.
