A scientific hypothesis is a predicted statement proposed on the basis of previous work related to the scientific question. Therefore, the scientific hypothesis is also known as an educated guess.
A scientific hypothesis is designed in a way that it contains the possibility which explains the natural phenomenon to an extent which could be tested through the experiments.
Since the hypothesis explains the phenomenon without testing which is done later through experiment therefore scientific hypothesis is the correct answer.
It is a scientific hypothesis. A scientific hypothesis must be testable, however there is a significantly more grounded necessity that a testable speculation must meet before it can truly be viewed as logical. This foundation comes essentially from crafted by the rationalist of science Karl Popper, and is called "falsifiability".
