Correct answer: A

  1. Image formed by a standard plane mirror

A standard flat mirror is a plane mirror. The image formed by a plane mirror has the following properties:

  • It is virtual, not real.
  • It is erect.
  • It is of same size as the object.
  • It is laterally inverted.
  1. Check each statement

  • A. Real ightarrow ightarrowightarrow False
    A plane mirror forms a virtual image.

  • B. Erect ightarrow ightarrowightarrow True
    The image is upright.

  • C. Smaller in size than object ightarrow ightarrowightarrow False
    The image is the same size as the object.

  • D. Laterally inverted ightarrow ightarrowightarrow True
    Left and right are reversed.

  1. Select the correct combination

The correct statements are B and D only.

So the correct option is:

A\boxed{\text{A}}A​

  1. Comparison with stored correct answer

Stored correct answer = A
Derived answer = A

Hence, they agree.
