The answer is: letter D, using reason and observation to solve a problem.
Explanation:
Renee Descartes was a French philosopher who founded the modern philosophy while Francis Bacon was an English philosopher who developed the scientific method. According to both of them, a critical step in reaching a sound scientific conclusion is by using reason and observation in order to solve it.
Observation and perceptual experiences co-existed in order to predict the outcome. In order to solve a problem,<u> the necessity to reason out is important. </u>The solution needs to have a reason in order to aid the readers how the researcher came up with it.

Answer:
Independent variable
Explanation:
In a scientific experiment, the variable that an experimenter varies or controls is called an independent variable. This variable has a direct impact on dependent variable.
In the question, Rachel wants to test how sunlight impacts plant growth over time. Now as sunlight impacts plant growth this means sunlight is an independent variable whereas the plants are dependent variable as the amounts of sunlight impact the plants. Also Rachel changes/varies or controls the amounts of sunlight to different sets of plants. Hence from the above definition of an independent variable it is clear that sunlight is an independent variable.
