What is true about the behavior of a red solution regarding light absorption?

A red solution primarily absorbs light in the blue-green spectrum, which is why it appears red to the human eye. The color we perceive is the result of the wavelengths of light that are not absorbed by the solution. When a solution appears red, it indicates that it reflects or transmits red wavelengths while absorbing those in other parts of the spectrum, particularly in the blue-green region.

This principle is grounded in the concept of complementary colors; red is opposite blue-green on the color wheel. Therefore, a red solution absorbs the wavelengths that correspond to blue and green light, making option C the accurate representation of its behavior concerning light absorption.

The other options do not accurately reflect the properties of a red solution in relation to light absorption. For example, stating that it absorbs predominantly red light contradicts the reason we perceive the solution as red. Similarly, indicating that it absorbs all wavelengths equally would not explain the selective absorption that accounts for the color we see. The mention of UV light transmittance is irrelevant to the color perception and typical behavior of colored solutions, as UV light is outside the visible range for human eyes.
