A good conclusion - Option B
A statement that is considered to be an answer to a research question should be included in a good conclusion. This is because a good conclusion must have all the reasons and explanations about the experimen. However, if there is no logic then it will create problems and will not be proved so there must be an appropriate reason or any logic.
An if-then statement that assumes a hypothesis is true. A warning to anyone who might consider criticizing the experimental data and an analysis of why a previous experiment was flawed should not be included in a good conclusion.
