Answer

Brief Explanations:

Some inks contain substances that can absorb energy from light (such as ultraviolet - light in sunlight). When they absorb this energy, they can undergo a change that makes them visible. Light is a form of energy and can interact with materials in ways other than just warming them up. It is incorrect to say light is not a physical thing as it has properties like energy and momentum. Also, light doesn't pull energy out of the ink to make it visible, but rather supplies energy to the ink.

Answer:

C. Yes. The ink can take in energy from the light, causing it to become visible.
