B is most likely the answer. Hope this helps.
Answer: In the proposed case, the light absorption is the variable to be understood <em>- </em>that is, the dependent and aimed observation<em> -</em> by exposing the pigment - the ready thing -, to the four picked color lights in a given experiment.
It can also be inferred about the other hidden concept in the question: controlled variables. Those are the different light colors, because there is choice and control of application of this parameter in the experiment. The pigment came ready, but the lights are chosen to test the light absorption.
Therefore, if the<u> light absorption is the dependent</u>, and the lights are the controlled, <u>the pigment rests as the independent variable.</u>
⇒The pigment is the independent variable, the light absorption is the dependent. (and the lights the controlled variable)

Answer:
Temperature inversions
Explanation:
<u>Temperature inversions</u> can act as a lid or trap, thus worsening air-pollution problems.
Temperature inversion is an increase in air temperature as it rises with respect to ground height. As the temperature inversion rises, so does the air density. Toxic and bad pollutants can occur in this area itself.
Since the temperature inversion is stable and windless it will remain at one particular height <em>collected with all the negative substances</em>. This is further referred to polluted air and often occurs in large, heavily populated cities.
