Solution

The correct option is C $C a C l_{2}$
The brick red colored flash of the firework is due to presence of calcium chloride. Same color is obtained in the flame test of calcium chloride. It is due to the excitation of electrons by the thermal energy which is then followed by de-excitation of electron to ground state along with liberation of light in the visible range.
