Answer: Option (d) is the correct answer.
Explanation:
A hypothesis is referred to as an idea which might be a possible explanation for a particular experiment or situation but it is not necessarily correct.
So, in order to form a hypothesis, a scientist has to theoretically look into the problem so that he can provide or suggest a possible explanation for the same.
This is because when the scientist looks theoretically into a problem then he will check all the steps in detail and its possible outcomes or results. This will lead to a possibility that the suggested hypothesis will be correct.
