Question

the temperature that bacteria multiply the fastest is: 100°c (212°f) 70°c (158°f) 37°c (98.6°f)

Explanation:

Bacteria multiply fastest at body temperature. The normal human body temperature is approximately \(37^{\circ}C\) (\(98.6^{\circ}F\)). Temperatures like \(100^{\circ}C\) (\(212^{\circ}F\)) are too hot (boiling point of water) and \(70^{\circ}C\) (\(158^{\circ}F\)) is also much higher than the optimal for bacterial growth in the context of the human body - related environment where such a question is likely framed (e.g., in food safety related to human consumption or internal body - related bacterial growth discussions).

Answer:

\(37^{\circ}C\) (\(98.6^{\circ}F\))
