Answer: B

Explanation:

In residential occupancies like townhomes protected under NFPA 13D, the design often includes the calculation of sprinkler coverage based on specific design areas and spacing rules. For a typical room layout, especially with flat and smooth ceilings, at least 2 sprinklers might be required to be calculated to ensure adequate coverage, considering possible obstructions and the layout of living spaces.
