D. Allow light to pass through the partially.

Answer 1

Hint: To get a clear idea about transparent substances you can think of its examples like the lens, soap bubbles, etc. Now you can easily relate these substances to their behavior with light.

Complete step by step answer:

Let’s discuss all the options one by one,

Options A and C, the substance absorbs all the light incident on them. That means these are not capable of having light pass through them. We call them opaque substances. An example of opaque is the quality of a black sheet of paper.

Option B, the substance allows light to pass through them. We call them transparent substances. Transparency is the physical property of allowing light to pass through the material without an appreciable scattering of light. Examples of transparent items are glass, water, and air. Hence, this option is correct.

Option D, the substance allows light to pass through them partially. We call these substances translucent substances.
Therefore, we can conclude that the correct answer to this question is option B.

Note: Do you know that transparency can provide the almost perfect camouflage for animals able to achieve it. This is easier in dimly-lit or turbid seawater than in good illumination. Many marine animals such as jellyfish are highly transparent.
