Final answer:
Pathogens grow the fastest in the temperature range of 40°F - 140°F (4°C - 60°C).
Step-by-step explanation:
The temperature gap in which pathogens grow the fastest is 40°F - 140°F (4°C - 60°C) (option A). Bacteria generally multiply most rapidly at temperatures between about 4 and 60 degrees C (40 and 140 degrees F). Perishable foods that remain within that temperature range for more than two hours may become dangerous to eat because of rapid bacterial growth.
