Thomas and Dianne Stewart, out for an afternoon drive, stopped at a stop sign in a quiet suburban neighborhood. Thomas watched a little girl, perhaps two years old, as she played in her yard. Moments later he gasped when he realized she was playing with a cigarette lighter. "How utterly awful it is to let a small child play with a cigarette lighter," Thomas exclaimed to his wife. His wife nodded her head in agreement. As he prepared to pull away, he watched the little girl head into the back yard. As the car began to move, Thomas spotted a large red gasoline can, with no lid on it. If the girl flicked the cigarette lighter, the spark or resulting flame could ignite the fumes escaping from the open gas can, creating a high potential for disaster. Thomas, trained in safety and rescue operations while in the army, trained in the martial arts while in college, a marathon runner, weight lifter, and Olympic swimmer, sprang into action. He kicked his car door open, and instructed his wife to take the fire extinguisher in the car. She nodded her head and followed him with the equipment he needed. He removed the tab, activating the extinguisher and directed her to spray the small child as if were in flames. Dianne aimed the nozzle at the baby and pulled the trigger. Mushrooming foam covered the little girl from her head to her toes, protecting her from the flames, in the event of an explosion. The little girl began crying, not aware that these two people were risking their very lives for her. From the side of the house, Thomas and Dianne heard the child’s mother yell, "Jessica, do you need more candy in your Pez dispenser" The couple looked again at the object in the little girl’s hand, and then rushed to their car and hightailed out of the neighborhood. Why did the couple spray the baby with foam
A. The baby was in flames.
B. The baby’s life was at risk.
C. They meant to save her from an explosion.
D. They tried to stop the baby from getting close to the open gas can.
