A scientific hypothesis must be **testable**. Here's a breakdown of the options: 1. **A random guess**: This is not a scientific hypothesis. A hypothesis should be based on existing knowledge and observations, not just a random guess. 2. **An if/then statement**: While many hypotheses are formulated in this way, it is not a strict requirement. A hypothesis can be stated in various forms, but it should still be testable. 3. **Correct**: A hypothesis does not need to be correct. The purpose of a hypothesis is to be tested through experimentation and observation. It can be proven wrong. 4. **Testable**: This is the key characteristic of a scientific hypothesis. It must be possible to test the hypothesis through experiments or observations to determine its validity. In summary, the most accurate answer is that a scientific hypothesis must be **testable**.
