Final answer:
In the scientific process, a hypothesis is a testable statement or explanation put forth to explain observations, which can be supported or refuted through controlled experimentation.
So the correct answer is A) hypothesis
Step-by-step explanation:
In the scientific process, a hypothesis is a statement or explanation of certain events or happenings. A hypothesis provides a testable explanation for observations, and it is generated after making observations but before conducting experiments. In essence, it's an educated guess about the relationship between variables that can be supported or refuted through experimentation.
For example, if one observes that salt seems to dissolve quicker in hot water compared to cold, a possible hypothesis could be that 'heat increases the rate at which salt dissolves in water.' This hypothesis can then be tested through a controlled experiment, where variables are manipulated to see if the results are consistent with the hypothesis.
the correct answer is option A
