Answer:
The correct answer is hypothesis.
Explanation:
An explanation, which is proposed, and which is accepted temporarily in order to look for an observed phenomenon is considered as a hypothesis. At certain occasions, it is also illustrated as an educated guess.
A hypothesis is an initial step, which is taken by the scientists at the time of the scientific investigation and it functions as the ground on which the scientific investigation is reliant upon. A hypothesis needs to be testable, and the illustration provided about it must be based on previous scientific knowledge.
