The correct answer is:
A-II, B-I, C-IV, D-III
The colours of the flame are produced because of the movement of the electrons in the metal ions present in their salts. Calcium exhibits a brick-red colour. Strontium exhibits crimson colour. And the barium exhibits an apple green colour.
K is an alkali metal. Potassium is colourless or white but when it is heated, it produces a violet flame due to the excitation of the electrons to the higher energy orbitals. Potassium burns with a light purple-coloured flame.
So, the correct option is C
