Solution:
It is use as the scientific method to make testable explanations and predictions about the world. A scientist asks a question and develops an experiment, or set of experiments, to answer that question. Engineers use the engineering design process to create solutions to problems.
Both have the clearly defined steps are as follows:
State your question Define the problem
Do background research Do background research
Formulate your hypothesis, identify variables Specify requirements
Design experiment, establish procedure Create alternative solutions, choose the best one and develop it
Test your hypothesis by doing an experiment Build a prototype
Analyze your results and draw conclusions Test and redesign as necessary
Communicate results Communicate resul
Thus the right answer is A.
