Temperature range (F) of the danger zone
A
10-100
B
20-220
C
139-149
D
40-140
Explanation: 

Detailed explanation-1: -Bacteria grow most rapidly in the range of temperatures between 40 °F and 140 °F, doubling in number in as little as 20 minutes. This range of temperatures is often called the “Danger Zone.” Never leave food out of refrigeration over 2 hours.

Detailed explanation-2: -The temperature range in which disease causing bacteria grow best in TCS food is called the temperature danger zone. The temperature danger zone is between 41°F and 135°F. TCS food must pass through the temperature danger zone as quickly as possible. Keep hot food hot and cold food cold.

Detailed explanation-3: -The temperature range at which disease-causing bacteria grow best in time/temperature control for safety food (TCS) is called the temperature danger zone. Temperature danger zone is between 41°F and 135°F.

Detailed explanation-4: -It’s important to keep perishable foods above 140°F or below 40°F (greater than 60°C or less than 4°C) to prevent the growth of harmful pathogens. The temperature danger zone is the temperature range of 40–140°F (4.4–60°C). Bacteria and pathogens thrive in this temperature range.
