Option (A)Forms a hypothesis.A hypothesis is a description of a supposed or proposed explanation made on the basis of limited evidence. During a scientific method, a hypothesis is proposed and then it is further tested. Thus, a hypothesis is created before any applicable work or research has been done. So, this is an incorrect answer.

Option (B)Publish result. The experiments are evaluated through the scientific methodology and after experiment, observation and inference, final result is deducted. The scientist then finally communicates their research results to the scientific community. So, this is an incorrect answer

Option (D)Peer review. Scientists after successful completion of research projects publish their results in peer-reviewed journals which enables to examine the findings themselves. It also provides instructions so that other scientists can repeat, verify and confirm the results.So, and this is an incorrect answer.
