True

Explanation:

One of the strong proponent to support a hypothesis is its ability to be falsifiable. Also, a hypothesis must be testable. To truly test a hypothesis, one must be able to prove it wrong. If a hypothesis cannot be proven wrong, then it is a very good hypothesis and can be made a theory. A good hypothesis is one that cannot be falsifiable and can be easily tested in an experimental set up.
