A medical patient is suffering from mysterious fainting spells. A medical team works to get to the bottom of the problem and identify the cause. So the correct option is B.
<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.

The structure of archaeal RNA ploymerase has more resemblance with RNA polymerase II of eukaryotes. The RNA polymerase of bacteria requires sigma factor for transcription initiation whereas the RNA ploymerase of archaea requires transcription factors for transcription initiation just like eukaryotes.
