  • A
    Convex mirror, Real image
  • Convex mirror, Virtual image
  • C
    Concave mirror, Real image
  • D
    Concave mirror, Virtual image

Answer

Correct option: B.
Convex mirror, Virtual image
b
Sine magnification is $-2$ so virtual object have virtual image.
virtual object to virtual image then mirror is convex.
