Answer:
Experimental Research.
Explanation:
Experimental research is a research method based on scientific approach. The research helps to understand the cause-and-effect relationshio between the two variables, namely independent and dependent. Independent variable manipulated while dependent variable remains constant.
<u>In the given case, Caterpillar is using the experimental research method. Caterpillar is trying to understand the cause-and-effect relationship between the two variables-- the operators and two types of steering mechanisms, in which dependent variable-- the operators, remains constant, and steering mechanisms is manipulated.</u>
Thus the experimental research method is the correct answer.
