We can see a non-luminous object when the light
$(a)$. emitted by the object falls on the eye
$(b)$. is reflected from the object towards our eye
$(c)$. completely passes through the object
$(d)$. gets completely absorbed by the object

Academic Physics NCERT Class 8

A non-luminous object can be seen by us when the light is reflected from the object towards our eye.

So, option $(b)$ is correct.
