Detailed explanation-1: -A. Under Control A controlled experiment tests only one factor at a time and consists of a control group and one or more experimental groups.
Detailed explanation-2: -Each controlled experiment looks at the effect of one variable (the independent variable) on some event or condition (the dependent variable). So the independent variable is the factor being tested and the dependent variable is the factor being observed and measured.
Detailed explanation-3: -What is the difference between a control group and an experimental group? An experimental group, also known as a treatment group, receives the treatment whose effect researchers wish to study, whereas a control group does not. They should be identical in all other ways.
