Answer 1

C. Experimental group

Basically the experiment has to be done with proper reasoning to make the scientific explanation satisfactory for all concerned. Scientific method is a process that is ongoing. Based on the observations via properly done experiments, a scientist can come to a proper conclusion. Although the procedures followed during experiment may vary, but the final result should always be the same. 

Answer 2

Answer: C. Experimental group

Explanation:

A controlled experiment is a scientific test in which a single variable can be directly manipulated to know the effect of manipulation over the variable under study. A control variable is used over which no manipulation is performed. It is kept as a benchmark for comparison of observations by using the control and experiment group in an experiment.

An experiment group is a set of independent variables over which the tests are performed in a controlled experiment.
