Final answer:

L. monocytogenes grows faster at 35°C compared to room temperature, as its optimal growth usually occurs near human body temperature.

Step-by-step explanation:

The question asks whether L. monocytogenes grows faster at room temperature (RT) or at 35°C. L. monocytogenes is a psychrophilic organism, meaning it can grow at lower temperatures, and is also halotolerant. It is known for its ability to multiply at refrigeration temperatures (4-10 °C), which are much lower than room temperature.

However, optimal growth of many bacteria, including L. monocytogenes, typically occurs near the human body temperature, which is around 37°C. Therefore, the correct answer is that L. monocytogenes grows faster at 35°C than at room temperature.
