A. Collecting samples to analyze is expensive

Explanation:

Experimental research designs may be referred to as an analytical approach which is based on establishing a scientific hypothesis through by subjecting observations or subjects to certain treatment carried out in a controlled environment. In a typical experimental research design, we have two groups which are the constant group or observation and the variable group which are the actual experimetal group which are subjected to treatment and whose behavior are compared to that of the constant group. From the options given, one actual limitation of the experimetal research design is the associated cost particularly those which require longer time to study and analyse. Other limitations include ; difficulty in measuring human response and skepticism over applicability of findings in a natural environment.
