• Option b: A hypothesis should be falsifiable (able to be proven wrong), which is a key characteristic, so this is true.
• Option c: To be tested, a hypothesis should lead to measurable results, so this is true.
• Option d: A hypothesis is a proposed explanation that can be supported or refuted by evidence; it does not always have to be true. It's a tentative statement, and experiments can show it's incorrect. So this statement about a hypothesis is not true.

Answer:

d. It always has to be true
