Answer = A

Explanation:
When Ba⁺² is subjected to flame it burns yellow-green under the flame. This colour is generated due to the fact that on exposure to heat the electrons of metal absorbs energy and gets excited to higher energy level, and bounce back to ground state with the elimination of energy absorbed. This energy of particular wavelength falls in visible region and gives yellow-green colour. When compounds of Barium chloride and Barium Sulphate are subjected to flame the give same colour.
