Answer: A

Explanation:

For a building where the maximum ceiling temperature will be 80°F (26°C), the lowest permissible temperature classification for the sprinklers would be "Ordinary." This is based on the color-coding system for sprinklers, which provides a means to identify the temperature classifications of their operating elements. Each temperature classification corresponds to a range of maximum ceiling temperatures for which the classification is allowed to be installed. The "Ordinary" classification is suitable for environments where the ceiling temperatures do not exceed the lower thresholds, making it appropriate for a maximum ceiling temperature of 80°F (26°C).
