Final answer:
About 50 of the 100 aliens would become thin if the temperature were 35°C.
Step-by-step explanation:
To determine how many of the 100 aliens would become thin if the temperature were 35°C, we need to analyze the given data. From the options provided, we can eliminate option a as it suggests 0% of the aliens would become thin, which is unlikely. Option c suggests that all 100% of the aliens would become thin, which is also unlikely. Option d suggests that more than 100% of the aliens would become thin, which is impossible. Therefore, option b, which suggests that about 50 aliens would become thin, is the most reasonable choice.
