An achromatic combination of lenses produce:

  • A
    Images in black and white
  • B
    Colored images
  • C
    Images unaffected by variation of refractive index with wavelength
  • D
    Highly enlarged images

  1. Images unaffected by variation of refractive index with wavelength

Explanation:

An achromatic combination of lenses provide deviation without dispersion. So, images are unaffected by variation of refractive index with wavelength.
