Step 1: A book is a non-luminous object (it does not give off its own light). Step 2: Light from a source (like a lamp) strikes the book. Step 3: The book reflects this light into our eyes, allowing us to see it.

Correct answer: Light from the light source reflects off the book and enters our eyes.
