The question is asking "which of the following objects will you not see a reflection?".
A distinction (albeit poorly) is being made between specular reflection and diffuse reflection.
The objects in options 1-3 will exhibit specular reflection, while option 4 "a book" will exhibit diffuse reflection. So the correct option will be "4 Book" since this object will not exhibit specular reflection, whereas "1. Polished metal, 2. Mirror" and "3. Undisturbed water" all exhibit specular reflection.
You are correct and the question should probably have been worded similar to this:
"Which of the following objects would exhibit diffuse reflection, as oppose to specular reflection?"
Now with the understanding that the question posed by the teacher was probably at an elementary school level, it should be noted that a more technical answer (and more accurate answer) should explain these two forms of reflection in detail, so see more in the links below. But to briefly summarize:
Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection.
Specular reflection is described as:
Specular reflection, or regular reflection, is the mirror-like reflection of waves, such as light, from a surface.
