The question is asking "which of the following objects will you not see a reflection?".
I think the teacher was trying to get at which objects reflect back most of the incident light, as oppose to objects that scatter (in random directions) most of the incident light.
You are correct and the question should probably have also been asked this way:
Of the following objects, which reflect significantly more light than they scatter?
Or better yet
Which of the following objects would cause diffuse reflection (as oppose to mainly 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.
From Wikipedia Diffuse reflection:
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.
And this link from Wikipedia, specular reflection is described as:
Specular reflection, or regular reflection, is the mirror-like reflection of waves, such as light, from a surface.
