Final answer:
The single best answer to the question is A: A scientific hypothesis is not able to be proven true absolutely; it must instead be falsifiable, which means it can be proven false.
Step-by-step explanation:
A scientific hypothesis has several features, but it is not able to be proven true in the absolute sense; rather, it is able to be falsifiable which means it can be shown to be false through testing. Therefore, the correct answer to the question is A: A scientific hypothesis is able to be proven true. Other key features of a hypothesis include that it is a possible explanation for something, based on observations, and can be tested through experimentation or further observation.
Scientific hypotheses are tentative and can be easily changed or refined based on new evidence. They must be testable so that scientific experiments can validate them, which is a process that involves making predictions and then conducting experiments or making observations to see if the predictions hold true.
