Final answer:
The scientific statement is B. The statement about plants eating meat, as it is based on observable and testable evidence of carnivorous plants. The statement about extraterrestrial beings does not currently have supportable evidence and is not considered scientific.
Step-by-step explanation:
To determine which statement is scientific, we need to consider the evidence and ability to test the hypothesis. The first statement about plants eating meat is scientific because there is substantial evidence for such plants, known as carnivorous plants, which have mechanisms to trap and digest insects and other small creatures. This claim can be and has been observed and tested through scientific methods.
On the other hand, the second statement about extraterrestrial beings visiting Earth, although it can be a topic of scientific inquiry, currently lacks credible evidence and a means to test it through repeatable experiments or observations. Therefore, the statement about extraterrestrial beings is not currently considered scientific.
Given this analysis, the correct answer is B. The statement about plants eating meat is scientific because it is supported by scientific evidence and can be tested, whereas the claim regarding extraterrestrial beings cannot be presently tested or substantiated.
