Answer 2

The correct answer is option (b). polished.

• The completed sentence is, "A mirror has a polished surface."

• A mirror is a smooth, flat, and shining surface that has the ability to reflect the light that falls on it.
• The word "polished" means "being shiny as a result of rubbing."
• This in itself explains the surface of a plane mirror, or simply a mirror.
• The word "rough" refers to surfaces that are irregular and smooth.
• The term "rough" doesn't depict a mirror surface, and hence option (a) is incorrect.
• The term "dark" refers to the absence of light, which is not related to a mirror.
• Hence, options (c) and (d) are also incorrect.
