<h3>What is the scientific method?</h3>

The start of a scientific investigation is observation. This means anything that catches the attention of the scientist. For example, for a  cancer biologist, a certain kind of cancer might be an observation that can't be treated with chemotherapy and he would wonder why it is so.

For all the sciences, the core is a problem-solving approach which is called the scientific method. There are five basic steps in the scientific method. These are:

  • Observation of a phenomenon
  • Questioning the reason or cause for it.
  • Hypothesizing or giving a testable explanation
  • Making a prediction based on the hypothesis.
  • Testing the prediction.
  • Using the results to develop new hypotheses or predictions.

Therefore, the correct option is B.
