this was a tricky question. I got the answer wrong at first too!

see we all know different properties of images formed by converging lens! this question asks about a DIVERGING lens. The properties of image formed by DIVERGING LENS are :
  1. Virtual(same side of lens)
  2. Upright
  3. Diminished
  4. Closer to lens than object
Use the first and fourth property to find the answer!
