Under what condition will the results of an experiment based on a hypothesis most likely lead to new experimentation?

when the results support an existing theory
when the results support an existing law
when the results do not match the experimenter’s predictions
when the results agree with the experimenter’s predictions

The condition that would make an experiment based on a hypothesis might lead to new experimentation is: when the results do not match the experimenter’s predictions

Before experiment began, the researchers would make a predictions based on what they know on current knowledge.

When the results do not match the prediction, the researchers would know that there is some factors  or irregularities that caused the misprediction, Because of this, new experimentation would most likely conducted to find out about these factors.
