What is the upper bound of the temperature danger zone in Fahrenheit?

Explanation:
The temperature danger zone is the range where bacteria multiply rapidly, typically from 40°F up to 140°F. The upper bound is 140°F because above this temperature, the growth of most bacteria slows significantly or they are killed, so foods should be kept above 140°F when hot or cooled below 40°F to stay out of the danger zone. The other options fall outside this upper limit: 100°F is still within the danger zone, while 160°F and 180°F are above it, where cooking temperatures help kill bacteria rather than represent the zone where they rapidly grow.
