Final answer:
The 1991 San Francisco Bay Area fire was initially controlled but was reignited by strong winds.
Step-by-step explanation:
The 1991 San Francisco Bay Area fire was initially controlled, but it was reignited by strong winds (option A). Strong winds can fan the flames, spreading the fire and making it harder to control. In the case of the San Francisco Bay Area fire, the strong winds reignited the fire and caused it to spread further, resulting in more damage and destruction.
