Answer:
The correct answer would be - "if then" statement.
Explanation:
A hypothesis is an assumption about a natural phenomenon of the natural world based on pre-existed studies or evidence. A hypothesis is made to solve a problem or gathering knowledge about a particular question and it is made to test if it is true or not.
The conclusion of a hypothesis can be refined by the "if then" statement as it allows clearing the picture about cause and conclusion in a single sentence.
Thus, the correct answer is - "if then" statement.
