$<font color = black > here we go....$


⊙ We know that a plane surface can reflect a ray of light.


⊙ If we take option A ( A wooden board ) then light can't be reflected as if has ups and downs in its surface. It is not plain.


⊙ If we take option B (a glass sheet) it too can't reflect the light as it is not fully plain surface.


⊙ If we take option D ( White paper ) It can't reflect light as it has ups and downs in its surface and it is not plain.


⊙ BUT , if we take option C (A mirror ) it will get the patch of light as mirror has the plain surface. Even we use mirror to show the principle of Reflection of light.


So, answer is option C


Hope it helps you
