The heat and the light are equal to the chemical energy spent.
Option A.
Explanation:
A flash light is a perfect example of conversion of energy from chemical energy to electrical energy or light energy. And just like every case, some energy is lost as heat energy.
Here in the diagram we can see that the wire carries the electrical energy from the cells which contains energy as chemical energy.
Then the wire gets attached to a bulb where the electrical energy gets converted into light energy. And as a result of resistance, heat energy is emitted from the wire.
