The correct answer is a hypothesis
In the scientific method, a hypothesis can be defined as the provisional or attempted solution to a given problem. The level of truth attributed to such a hypothesis will depend on how the empirical data collected support or not what is stated in the hypothesis. This process, known as empirical contrasting of the hypothesis, can be carried out through confirmation (in the case of universal hypotheses) or verification (in the case of existential hypotheses).
