So, For this purpose, we know that the
An independent variable is the variable you manipulate, control, or vary in an experimental study to explore its effects.
And
We know that the
The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
Due to this reason the variation in the independent variable is 0.81%.
So, The variation in the independent variable is 0.81%. Thus option C is correct option.
